Question

Suppose the circumference of a circle is 8π

. What is its area?

Answer 1

Well, its diameter would be 8, making its radius 4. The formula for finding the area of a circle is π x radius^2. So, the area would be ^2.

Answer 2

Circumference = (π) x (diameter)
Circumference = 8π
(π) x (diameter) = 8π
Diameter = 8
Radius = 4

Area = π x (Radius)²
Area = π x (4)²
Area = π x (16) = 50.27 units² (rounded)
