Answer:

Volume-- 3053.6

Surface Area- 1017.88

Step-by-step explanation:

A=4πr2=4·π·92≈1017.87602

V=4

3πr3=4

3·π·93≈3053.62806

Answer:

Step-by-step explanation:

Surface area:  A = 4πr².  If r = 9 in, then the surface area is

4(3.14)(9 in)² = 1018 in²

Volume:  (4/3)πr³.  Here, V = (4/3)(3.14)(9 in)³ = 3052 in³
