Question

A sphere that is 18 inches across has what volume?

Answers

GPT 3.5
The volume of a sphere is given by the formula V = (4/3)πr^3, where r is the radius of the sphere. Since the diameter of the sphere is 18 inches (which means the radius is half of that), the radius is 9 inches.

Plugging the radius into the formula:

V = (4/3)π(9)^3
V = (4/3)π(729)
V = 3053.63 cubic inches

Therefore, the volume of the sphere is approximately 3053.63 cubic inches.
