What is the approximate volume of the model of planet earth? the radius is 3ft and use 3.14 to approximate pi. round to the nearest hundredth if necessary.

Work Shown:

The formula to use to find the volume of a sphere is

V = (4/3)*pi*r^3

In this case, r = 3 is the radius. We'll use the approximation pi = 3.14

This means,

V = (4/3)*pi*r^3

V = (4/3)*3.14*3^3 plug in r = 3; pi = 3.14

V = 113.04 use your calculator

The units are in cubic feet. Think of a 1 ft by 1 ft by 1 ft cube block. A sphere can be sub-divided into smaller cubes to get an approximation.
