Question

Find the volume of the following solid figure. Use = 3.14.

V = 4/31r. A sphere has a radius of 4.5 inches.
Volume (to the nearest tenth) =
cubic inches

A. 56.5
B. 381.5
C. 84.8

Answer 1

B. 381.5

Explanation:

`r = 4.5\\\pi = 3.14\\\\V = ?\\\\Volume = (4)/(3) \pi r^3\\\\V= (4)/(3) * 3.14 * (4.5)^3\\\\V = (4)/(3) * 286.1325\\\\V = (1144.53)/(3) \\\\V = 381.51\\\\Volume = 381.51 \: inches^3`
