Question

Find the volume of this sphere.Use 3 for TT.Va3[?]ft³9 ftV = 1/3r³

Answer 1

The Solution:

Given:

We are asked to find the volume of the given sphere.

Using the given formula:

`V=(4)/(3)\pi r^3`

In this case:

`\begin{gathered} r=radius=9ft \\ \pi=3\text{ \lparen given\rparen} \end{gathered}`

Substitute these values in the formula.

`V=(4)/(3)*3*9^3=4*9^3=2916\text{ }ft^3`

Therefore, the correct answer is 2916 cubic feet.
