Question

What is the area of the drumhead on the drum shown below? Round to the nearest 10th.14 inches

Answer 1

The formula for finding the area of a circle is

a = pi × radius^2

Since the diameter is 14 inches, the radius is 7 inches, so to solve...

a = pi × 7^2
a = 3.14 × 49
a = 153.86

Rounded to the nearest tenth...

153.9 inches^2
