## Parallelogram Law Of Vector Addition

Pressure Formula | Physics Animation

If we were to represent two vectors magnitude and direction by two adjacent sides of a parallelogram. The resultant can then be represented in magnitude and direction by the diagonal. This diagonal is the one which passes through the point of intersection of these two sides.

## How Do You Prove The Area Of The Circle

If a circle is folded into a triangle, the radius becomes the height of the triangle and the perimeter becomes its base which is 2 ×× r. We know that the area of the triangle is found by multiplying its base and height and then dividing by 2, which is: ½× 2 ×× r × r. Therefore, the area of the circle is r2.

## Area Of An Equilateral Triangle

## What Is The Surface Area Of A Cylinder

The surface area of a cylinder is the total region covered by the surface of the cylindrical shape. The total surface area of a cylinder is given as the sum of lateral surface area and the area of two bases. It is mathematically expressed as 2r and is expressed in square units, like m2, in2, cm2, yd2, etc. The curved or the lateral surface area of a cylinder is calculated with the formula, Curved surface area = 2rh.

## Surface Area Of A Square Pyramid • To find the total surface area, well first examine the area of the base, which is just a square. We know that the area of a square is , where b is the length of the side. In this case, the surface area is 6², or 36 square inches.
• Next, we look at the four sides, which are just triangles. We know the area of a triangle is just / 2, where b is the base and h is the height. In this case, the base of the triangle is the same as the base of the pyramid, b. The height of the triangle is equal to the slant height of the pyramid, s. So the area of just one of these triangular sides is equal to:
• When we add four of those triangles with the area of the square base, we have a total surface area of b² + 4 / 2, or b² + 2bs for the square pyramid. Plugging in the numbers gives us:

Physics is the most fundamental of all sciences. It is also one of the toughest sciences to master. Learning physics is basically studying the fundamental laws that govern our universe. I would say that there is a lot more to ascertain than just remember and mug up the physics formulas. Try to understand what a formula says and means, and what physical relation it expounds. If you understand the physical concepts underlying those formulas, deriving them or remembering them is easy. This ScienceStruck article lists some physics formulas that you would need in solving basic physics problems.

## Why Is The Formula For The Surface Area Of A Circle Not ^2

No, why would you think that? The explanation is simple: that’s simply not the correct area for the surface area of a circle.

NascentOxygen said:Where did you learn of that method? Does it work for any geometric shape, do you know?

nickadams said:yes it works with many shapes for area, surface area, and volume. Like for the area of a rectangle you could take a line that is the length between opposite edges longways and lay it side by side number of times and then multiplying the units together gives you the appropriate units^2 of area.

So in order to keep this approach for circles I would have to find the area of triangles made up of two radiuses set a certain angle apart and with the arc length subtending that angle as the third side. Then I could multiply these triangles by and get the area of the circle…

HallsofIvy said:By the way, am I the only one wondering why nickadams keeps saying “surface area of a circle” when he clearly means “surface are of a sphere“?

## How To Calculate Area

Let us see how to calculate the area of a shape with the help of a grid. The area of any shape is the number of unit squares that can fit into it. The grid is made up of many squares of sides 1 unit by 1 unit. The area of each of these squares is 1 square unit. Hence, each square is known as a unit square. Look at the figure shown below. Let us find the area of the shape drawn in the grid.

The area of this shape is the number of shaded unit squares.

Thus, the area of the shape = 9 square units. Now, let us look at another example. When the shape does not occupy a complete unit square, we can approximate and find its value. If it occupies about 1/2 of the unit square, we can combine two such halves to form an area of 1 square unit. Observe the figure given below.

Here, the area occupied by the shape = 4 full squares and 8 half squares. Together this forms an area of 8 square units. If the shaded region is less than 1/2, we can omit those parts. For regular shapes, we have certain formulas to calculate their area. Note that this is only an approximate value.

## Example Of Calculating Volume And Surface Area To find surface areas of objects with a curved surface, such as a sphere, there is no choice but to memorize the volume and surface area formulas. But for other objects, we can often break them down into other recognizable polygons and shapes whose volume or surface area we can easily find. For example, with a pyramid, you simply calculate the surface area of the base and add that to the surface area of each triangular side.

Let’s find both the surface area and the volume of a square pyramid with a base length of 6 inches and a slant height of 5 inches.

## Definition Of Length Area Volume

Length area and volume, Dimensional measures of one-dimensional, two- dimensional, and three-dimensional geometric objects. All three are magnitudes, that represent the size of an object. We can define length as the size of a line segment , the area is the size of a closed region in a plane, and volume is the size of a solid.

Formulas for the area as well as the volume are based on lengths. For example, the area of a circle equals times the square of the length of its radius , and the volume of a rectangular box is the product of its three linear dimensions that is: length, width, as well as height.

In this article, we are going to discuss length area and volume, volume with fractional edge lengths and unit cubes, differential length area and volume as well as measuring volume as area times length.

## Approximate Area By Counting Squares

Sometimes the squares don’t match the shape exactly, but we can get an “approximate” answer.

#### One way is:

• more than half a square counts as 1
• less than half a square counts as 0

Like this:

This pentagon has an area of approximately 17

#### Or we can count one square when the areas seem to add up.

Example: Here the area marked “4” seems equal to about 1 whole square :

This circle has an area of approximately 14

#### But using a formula is best:

## What Is The Formula For Surface Area

Calculating the Area under a Graph – GCSE Physics

The formula to find the surface areas of different geometrical shapes is to add the areas of each of their faces. It can be very tedious to find the area of each face individually, so we have surface area formulas for each of the geometrical figures. Some of the formulas are listed below:

• Total surface area of a cube = 6 × 2
• Surface area of sphere = 4r2
• Total surface area of cone = r

## Surface Area Of Prism

A prism is a 3D solid object made up of two congruent bases which are polygons and congruent lateral faces which are rectangular in shape. There are two types of areas that a prism has – the lateral surface area and the total surface area. The lateral area of a prism is the sum of the areas of all its lateral faces whereas the total surface area of a prism is the sum of its lateral area and area of its bases.

The lateral surface area of prism = base perimeter × height

The total surface area of a prism = Lateral surface area of prism + area of the two bases = + Lateral surface area = + .

There are seven types of prisms based on the shape of the bases of prisms. The bases of different types of prisms are different so are the formulas to determine the surface area of the prism. Observe the table given below to understand this concept behind the surface area of various prisms:
