Question

Find the area of the following circles. Leave your answer in terms of pi or round to the nearest 10th.

Answer 1

To find the area of a circle, we use the formula for area

A = pi r^2 where r is the radius

We are given the diameter

d = 2r

8 = 2r

Solving for r

8/2 =r

4= r

A = pi (4)^2

A = 16 pi
