How to find perimeter of circle when area is given?

If you know the area of the circle, you can find its perimeter The perimeter of a circle is the sum of the length of all its sides. So, divide the area by π to find the perimeter of a circle. To find the perimeter of a circle with the given area, use the circumference formula C = πr or C = 2πr. Here, C is the circumference of the circle, r is the radius, and π is the number Pi. If

How to find perimeter of circle without area?

There are many ways to find the perimeter of a circle. One of such way is to use the Pythagorean Theorem. The Pythagorean Theorem states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides. In our case, we will use the Pythagorean Theorem to find the perimeter of a circle.

How to find the perimeter of a circle given its area?

If you know the area of a circle and want to find the perimeter, you can use the Pythagorean Theorem. Just remember, the Pythagorean Theorem works only for right triangles.

How to find the perimeter of a circle given its area, radius,

All you need to do is find the length of the diameter which is the line drawn from the center of a circle to its circumference. The diameter equals twice the radius of a circle. A circle with diameter of 15 cm would have a radius of 7.5 cm. A circle with diameter of 30 cm would have a radius of 15 cm. You can find the circumference of a circle by multiplying the diameter of the circle by two pi. The two pi is a number that represents the circumference of a

How to find the perimeter of a circle given its area and radius?

One way to find the perimeter of a circle is by using the area-radius formula: P = 2πr. This equation will give you the perimeter of a circle with a known radius. To use the area-radius formula to find the perimeter given an area, you need to know the radius of the circle. By definition, the radius is the length of a line drawn from the center of the circle to any point on the circumference. If you know the area of a circle, you can
