Step-by-step explanation:

Answer 2

Answer:

B

Step-by-step explanation:

The volume (V) of a sphere is calculated using the formula

V = $\frac{4}{3}$ πr³ ← r is the radius

here r = 9, so

V = $\frac{4}{3}$ × π × 9³

   = $\frac{4}{3}$ × π × 729

   = $\frac{4(729)\pi }{3}$ = $\frac{2916\pi }{3}$ = 972 π m³
