The volume of a sphere is 1,200 ft3.

To find the radius of the sphere, we need to use the formula for the volume of a sphere:

V = (4/3)πr³

where V is the volume and r is the radius.

We can rearrange the formula to solve for r:

r = (∛(3V/4π))

Substituting the given volume V = 1,200 ft^3:

r = (∛(3(1,200)/4π))

Using a calculator:

r ≈ (∛(3(1,200)/4π)) ≈ 6.74 ft

Therefore, the radius of the sphere is approximately 6.74 feet.
