To find area given perimeter, rename perimeter to circumference and solve with these formulas: Circumference = 2πr (or 2 * π * r) Area = πr^2 (or π * r * r) With these the area can be found from circumference(or perimeter) as follows: A = π(C / 2π)^2 Now, to find the perimeter given the area; We use A = πr^2 and rearrange then solve: r = √(A / π) So, the circumference would be 2πr = 2π√(A / π)

The radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.

It is called perimeter.

If yo have the area of the circle, the square is irrelevant. Radius = sqrt(Area/pi)

Unless the area is a regular polygon (or a circle) you cannot.

For a given perimeter, the circle has the largest area possible.

In general you cannot find the perimeter of any shape if only the area is given.

The Perimeter of a circle is it's circumference. And the circumference is the diameter times pi. So to find the area, divide the circumference by pi, and get the diameter. Then divide the diameter by 2, to get the radius. Then multiply the radius times itself, and multiply that by pi.

If you are given the width and the perimeter, then figure out what the length is then calculate the area... hope this helps :)

Depending on the figure given you can find the area from the perimeter For example- If you have a square with a perimeter of 24, you divide 24 by 4 because all the sides of a square are congruent. In turn you will 6 as each side of the square The formula for the area of a square is side2 so you get 62 which is 36. The area is 36

More information is required in order to answer this question. What is the shape for which the perimeter is given? If it anything other than a circle or regular polygon it is not possible to determine the area. For a circle or regular polygon, the answer will depend on the shape.

There is insufficient information to answer the question. For a given area, the perimeter depends upon the shape. For a given area, the circle will have the smallest perimeter. For polygons, regular polygons will have a smaller perimeter than an irregular one of the same area. Also, for regular polygons, the greater the number of sides, the smaller the perimeter.

The area of a circle is described by the equations: A=πr2 and the perimeter of a circle is described by the equation: C=πd where: A is the Area C is the circumference, or perimeter r is the radius d=diameter=2r π= pi, the ratio of diameter to circumference (3.14159)

You cannot.

There is no perimeter of a circle. Only flat shapes have perimeters. You can however, find the circumference, surface area, and volume.
