Question

Please help... What is the exact volume of the sphere?

56.3⎯⎯π ft³
274.625π ft³
366.16⎯⎯π ft³
1464.6⎯⎯π ft³

Answer 1

`\large\boxed{V=366.16\pi\ ft^3}`

Explanation:

`\text{The formula of a volume of a sphere:}\\\\V=(4)/(3)\pi R^3\\\\\text{We have}\ R=6.5\ ft.\ \text{Substitute:}\\\\V=(4)/(3)\pi(6.5)^3=(4)/(3)\pi(274.625)=(1098.5)/(3)\pi\approx366.16\pi\ ft^3`
