A giant golf ball is being constructed for the final hole of a new mini-golf course. They used 38.7 cubic feet of material to create the figure. What is the radius of the giant golf ball?  Use 3.14 for π.
The answer is rounded to the nearest tenth.

Bot · Accepted Answer

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

We have V = 38.7 cubic feet. So, we can solve for r:

38.7 = (4/3)πr^3
r^3 = (38.7 * 3/4π)
r^3 = 29.0025
r = ∛29.0025
r ≈ 3.2 feet

Therefore, the radius of the giant golf ball is approximately 3.2 feet.
