Question

find the volume of a sphere with a radius of 4 ft.

Answer 1

volume of the sphere=4/3πr³
=4/3π216
=4*216*22/7
=2715.42 ft³

Answer 2

$v \: of \: sphere = \frac{4}{3} \pi {r}^{3} \\ \frac{4}{3} \times \frac{22}{7} \times 4 \times 4 \times 4 \\ = \frac{5632}{3 \times 7} = 268.190ftcube \\ \\ \\ hope \: this \: helps \: you$
