# Formula of Area and Perimeter

The formula of area and perimeter is very simple. It’s just Area = Pi * R^2 where “R” is the radius of the circle and “p” is the speed of light. The value for pi is fairly self-evident but the formula for area is a little more complicated.

Let’s take a look at how this varies as a function of radius, starting with integers. Integers are Numbers In elementary school, you may have learned that pi was approximately 3.14, but what you probably didn’t know was that it has other values too.

For example, 3.14 is not the only number that can be written as 3.14159…. In fact, there are integers other than 3.14 which also have values in the range of 1 to 8: 5/7 = 15/7 = 0 to 9/7 = 15/16 (rounded off to an integer value).

You can find out more about these numbers at lengthier lengths on Wikipedia . But even if you already know these numbers, they might not make much sense until you understand how they relate to areas and perimeters. Let’s explore!

## What is the formula for area?

The formula for area is simply Area = Pi * R^2, where “R” is the radius of the circle and “p” is the speed of light. Now, we’ll get into the nitty-gritty of it. As we move away from simple integers, the formula gets more complicated. We also need to take into account the “circumference” of the circle, which is the distance around the circle. What we have left over after we’ve factored out the “circumference” and the “radius” is the “area”. For example, the area of a circle with a radius of 5 sip * 5^2 = 56. The radii of the circles with different radii are different areas.

This formula is called “area formula” because we’re integrating the area (area along the long axis) of the circle. Like most important things in life, the formula for area is not perfect. There are places where the formula is slightly wrong or cannot be applied, such as when the circle is small or the speed of light is very high. You can see this and more with the equation-finder at Quiz let .

## What is the formula for perimeter?

The formula for perimeter is Pi * R^2, where “R” is the radius of the circle and “p” is the speed of light. Again, we’ll take a look at how this formula varies as a function of radius, starting with integers. For example, the perimeter of a circle with a radius of 3 is 3*Pi^2 = 6.

On the other hand, the perimeter of a circle with a radius of 7 is 7^2+8= 27. In between those two values is a “ Dubai Triangle ”, which has a perimeter of 51/7 = 3.6 and an area of π/7 = 0.25.

This formula is called “perimeter formula” because it’s integrating the “perimeter” (length of side) of the circle. Like most important things in life, the perimeter formula is not perfect either. There are places where it’s slightly off or the circle is not circumscribed. You can see this and more with the equation-finder at Quiz let .

## The area of a circle is Pi * R^2

The formula for area is simple, but the area of a circle is more complicated. The formula for area is just Area = Pi * R^2 where “R” is the radius of the circle and “p” is the speed of light.

To get a little more mathematical, the area of a circle is π * R^2, where “R” is the radius of the circle and “p” is the speed of light. This is called the “area formula” and is more accurate than the “Pi * R^2” formula. The area of a circle is about 2/3rds of the perimeter. The area of a rectangle is times the length of one side, and the area of a square is times the length of one side and one height (or width).

One potential problem with the area formula is that it doesn’t work if the speed of light is very high (like in a vacuum). When light travels at the speed of light in a vacuum, it’s not traveling in a circle. The formula can’t apply because the speed of light is a rate, not a volume. So, to avoid the high-speed-vacuum problem, we have to use the perimeter formula. This is where the equation-finder at Quiz let comes in. You can test yourself on the formula and find out how accurate it is.

## Perimeter of a circle = R^2

The perimeter of a circle is the length of the line connecting the center of the circle to the one point on the circumference. The formula for the perimeter of a circle is Pi * R^2. This is the same formula for the perimeter of a square that we discussed above. The only difference is that the square has two sides and the circle has one. Like the area formula, the perimeter formula is also slightly inaccurate. It has a couple of places where it’s slightly off. The main reason for this inaccuracy is that the formula is integrating “one side” of a circle. In reality, the perimeter of a circle is the length of one side of the circle.

## Conclusion

The formula for area and perimeter is simple. Area = Pi * R^2 where “R” is the radius of the circle and “p” is the speed of light. The value of pi is fairly self-evident but the formula for area is a little more complicated.
