What is the circumference of a circle with an area of 144 pie sq in?

To find the circumference of a circle with an area of 144π sq in, we first need to find the radius of the circle. The formula for the area of a circle is A = πr^2, where A is the area and r is the radius. Given that the area is 144π sq in, we can solve for the radius: 144π = πr^2, r^2 = 144, r = 12 inches. The circumference of a circle is calculated using the formula C = 2πr, so for a circle with a radius of 12 inches, the circumference would be 24π inches.
