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.
Each friend will get 1.35 pounds of pecans.
