The circumference of a lacrosse ball is 8 in. Find its volume to the nearest tenth of a cubic inch.

V = 8.6 in^3

Step-by-step explanation:

The circumference is given by

C = 2 * pi * r

8 = 2 * pi * r

Divide each side by 2pi

8 / 2pi = r

Using 3.14 for pi

1.27388535 = r

The volume of a sphere is given by

V = 4/3 pi r^3

V = 4/3 (3.14) (1.27388535) ^3

V = 8.654847391

To the nearest tenth

V = 8.6 in^3
