Answer:

7.2 feet

Step-by-step explanation:

The volume of a sphere is V = [tex]\frac{4}{3\\}[/tex][tex]\pi[/tex][tex]r^{3}[/tex]. In simple terms, you're cubing the radius, multiplying it to pi, and then multiplying 4/3.

Using the formula, we cube the radius of 1.2 feet.

1.2 x 1.2 x 1.2 = 1.728

Then, you multiply 1.728 with pi.

1.728 x [tex]\pi[/tex] = 5.42867210

Afterwards, you multiply 5.42867210 with  [tex]\frac{4}{3}[/tex].

5.42867210 x [tex]\frac{4}{3}[/tex] = 7.23822946667

Since the instructions say to round the nearest tenth, it becomes 7.2 feet.
