Question

The circumference of a circle is 15π centimeters. What is the area of the circle in terms of π?

Answer 1

Answer: 7.5²π square centimeters. OR 56.25π cm²

Explanation:

Circumference = diameter × π

So the diameter is 15 cm

Area = πr²

Radius is half the diameter, so 15/2 or 7.5

Area = (15/2)²π cm²
