To find the area of a circle, first we need to find the radius using the circumference.
The formula for the circumference of a circle is C = 2πr, where C is the circumference and r is the radius. Plugging in the given circumference of 72 cm:
72 = 2πr
r = 72 / 2π
r = 36 / π
r ≈ 11.46 cm
Now that we have the radius, we can find the area of the circle using the formula A = πr^2:
A = π(11.46)^2
A ≈ 412.96 cm^2
Therefore, the area of the circle with a circumference of 72 cm is approximately 412.96 square centimeters.
