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.

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


How do you find the perimeter when circumference is given?

When the shape is a circle, then the perimeter is called"circumference".The circumference IS the perimeter of a circle.

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


How do you find area when given perimeter and width?

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


How do you find the perimeter using area?

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


How do you determine perimeter if given the area?

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)


How do you find the area of rectangle given its perimeter?

You cannot.


How do you find area and perimeter of a circle?

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)


What is the area and perimeter of a cylinder?

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


How to find area and perimeter of circle?

The answer depends on what information you have about the circle. If you know the radius, thenArea = pi*r^2 and perimeter = 2*pi*r


Area of rhombus if area and perimeter is given and if you have to find altitude?

Perimeter = 4*Side so that Side = Perimeter/4 Area of a rhombus = Side * Altitude so Altitude = Area/Side = Area/(Perimeter/4) = 4*Area/Perimeter
