Question

a globe is a map of earth shaped as a sphere. what is the volume to the nearest tenth of a globe with a diameter of 16 inches

Answer 1

Using pi = 3.14

V = 2143.6 in ^3

If we use the pi button

V = 2144.7 in ^3

Explanation:

The volume of a sphere is given by

V = 4/3 pi r^3

We know the diameter is 16 so the radius is d/2 = 16/2 =8

V = 4/3 pi (8)^3

Using pi = 3.14

V = 4/3 * 3.14 * 8^3

=2143.573333

To the nearest tenth

V = 2143.6 in ^3

If we use the pi button

V = 2144.660585

To the nearest tenth

V = 2144.7 in ^3
