Answer:
382 ft³ (3 s.f.)
Step-by-step explanation:
![\boxed{volume \: of \: sphere = \frac{4}{ 3}\pi {r}^{3} }](https://tex.z-dn.net/?f=%5Cboxed%7Bvolume%20%5C%3A%20of%20%5C%3A%20sphere%20%3D%20%20%5Cfrac%7B4%7D%7B%203%7D%5Cpi%20%7Br%7D%5E%7B3%7D%20%20%7D)
Radius= diameter ÷2
Rdaius of sphere
= 9 ÷2
= 4.5 ft
Volume of sphere
![= \frac{4}{3} (\pi)(4.5)^{3}](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7B4%7D%7B3%7D%20%28%5Cpi%29%284.5%29%5E%7B3%7D%20)
= 382 ft³ (3 s.f.)
