Question

Find the volume V and surface area S of a sphere of radius 9 centimeters.

Answer 1

V = 972π cm³ (exact)

V = 3052 cm³ (approximate)

S = 324π cm² (exact)

S = 1017 cm² (approximate)

Explanation:

V = (4/3)πr³

S = 4πr²

V = (4/3)(π)(9 cm)³

V = 972π cm³ (exact)

V = 3052 cm³ (approximate)

S = 4π(9 cm)²

S = 324π cm² (exact)

S = 1017 cm² (approximate)
