Question

Find the area of a circle with a radius of 8

Answer 1

Circle area = pi*r^2
= PI*8^2 = pi*64
= About 3.14*64 = 200.96 square units

Answer 2

64π or 201.06

Explanation:

The formula for the area of a circle is A = πr². A is the area, and r is the radius.

Plug the radius, 8, into r and solve for A.

A = π(8)²

A = 64π

A = 201.06
