To find the area of a circle knowing only the circumference, you can use the formula A = (C^2) / (4ฯ€), where A is the area and C is the circumference. Square the circumference, then divide it by 4ฯ€ to get the area.

If the area of a circle is 201.06 then the circumference of the circle is?

The formula to find the circumference of a circle is C = 2ฯ€r, where r is the radius of the circle. To find the circumference, you first need to find the radius by using the formula for the area of a circle (A = ฯ€r^2). Given that the area is 201.06, you can solve for the radius. Once you have the radius, you can plug it into the formula C = 2ฯ€r to find the circumference.

How do you find the circumference if you have the area of a circle?

Area of a circle = 3.14 * r2 Thus, radius, r = root of ( Area of a circle / 3.14 ) --------- equation 1 Circumference of circle = 2 * 3.14 * r Therefore, from (equation 1), Circumference = 2 * 3.14 * root of ( Area of a circle / 3.14 ). In a nutshell, first find the radius and then the circumference.
