The formula for the area of a circle is A = πr^2, where A is the area and r is the radius.
We know that the area is 144π, so we can set up the equation as follows:
144π = πr^2
Dividing both sides of the equation by π, we get:
144 = r^2
Taking the square root of both sides, we find:
12 = r
The circumference of the circle is given by the formula C = 2πr, where C is the circumference and r is the radius.
Substituting the value of r, we have:
C = 2π(12) = 24π
Therefore, the circumference of the circle is 24π centimeters.
A circle has an area of 144 pi centimeters squared. Find the circumference.
