The formula for the circumference of a circle is C = 2πr, where r is the radius. Substituting 8.1 for the radius, we get C = 2 * π * 8.1 ≈ 50.92. Therefore, the circumference of the circle is approximately 50.92.

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 = 2πr, 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 = πr^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 = 2πr to find the circumference.
