Answer 1

Answer:

d=18 feet

Step-by-step explanation:

The volume of a sphere is represented by the equation $V=\frac{4}{3}\pi r$³, where r is the radius. If the volume is 972$\pi$,

$972\pi =\frac{4}{3}\pi r$³

Divide $\pi$ from each side,

$972=\frac{4}{3} r$³

Multiply each side by 3/4 to get rid of the fraction,

$r$³$=729$

Using the cube root, we find that 729 is actually a perfect cube.

$r=9$

Now, the diameter is 2 times the radius, so

9×2=18

So, the measure of the diameter is 18 feet.
