The formula for the area of a circle is A = πr^2, where r is the radius of the circle.
Given that C = 2πr, we can solve for the radius by rearranging the formula to r = C / (2π).
Substitute C = 12π into the formula to get r = 12π / (2π) = 6.
Now that we have the radius, we can calculate the area of the circle using the formula A = πr^2.
A = π(6)^2 = 36π
Therefore, the area of the circle is 36π.
If C=12π , what is the area of the circle?
