Use A = pi(r^2)

The diameter is 16 inches which means that the radius must be 6 inches.

radius = diameter divided by 2.

We now plug and chug and leave our answer in terms of pi. This means we do NOT use 3.14 for pi.

A = pi(6)^2

A = 36pi

Done!

Understood?

Area = pi%2Ar%5E2

Since diameter = 8 (16%2F2), then:

Area = pi%2A8%5E2, or highlight_green%2864%2Api%29
