Question

Hurry help plz exam 05 :The following sphere has a diameter of 11 inches.

What is the volume of the sphere? Use 3.14 for it and round your answer to the nearest tenth.
O 5,572.5 in^3
O 696.6 in^3
O 174.1 in^3
O 126.6 in^3

Answer 1

Answer:

696.6 in³

Step-by-step explanation:

The formula for the volume of a sphere is 4/3πr³

The diameter of 11 in. is given. Therefore, the radius is 5.5 (11/2 = 5.5).

1. Set up the equation

4/3(3.14)(5.5³)

2. Solve

= 696.6 in³

Answer 2

Answer:

$\boxed{Volume = 696.9 \ in.^3}$

Step-by-step explanation:

Diameter = 11 inches

Radius = 5.5 inches

Volume of sphere = $\frac{4}{3} \pi r^3$

Where r = 5.5 inches

Volume = $\frac{4}{3} (3.14)(5.5)^3$

Volume = $\frac{4}{3} (3.14)(166.375)$

Volume = $\frac{2090.7}{3}$

Volume = 696.9 in.³
