Question

The radius of a sphere is 3 inches. Which represents the volume of the sphere?

• 12t cubic inches
• 367 cubic inches
• 647T cubic inches
• 817 cubic inches

Answer 1

Explanation:

The formula for the volume of a sphere of radius r is V = (4/3)(pi)r^3.

Here, with r = 3 in, the volume is

V = (4/3)(3.14)(3 in)^2, or V = 36(pi)(27 in)^3 = 36pi in^3
