Explanation:

The formula for the volume of a sphere is V = 4/3 πr³.

So

Given

Volume (v) = 57ft³


v = (4)/(3) \pi {r}^(3)


57 = (4)/(3) * 3.14 * {r}^(3)


57 = (12.56)/(3) * {r}^(3)


57 = 4.19 * {r}^(3)


{r}^(3) = (57)/(4.19)


{r}^(3) = 13.6


r = \sqrt[3]{13.6}

Therefore r = 2.4 ft

I gave my answers by rounding off. so if you don't round off then it's answer is 2.3 ft
