A science museum has a spherical model of the earth with a diameter of 6.5 m. What is the volume of the model? Use 3.14 for and round your answer to the nearest whole number. Show your work.

To find the volume of the model of the Earth, you will use the formula (rule) for finding the volume of a sphere.

You will divide the diameter by 2 to get the radius. 6.5/2 = 3.25 m

V = 4/3 x pi x r^3

= 4/3 x 3.14 x 3

V = 143.72 cubic meters

The volume of the model is approximately 143.72 cubic meters.
