Volume of sphere is:

V = 4/3 πr³

r = radius
π = 3.14

18 is your diameter. To find radius, divide the diameter by 2
18/2 = 9

plug in 9 for radius

V = 4/3 (3.14)r³

V = 4/3(3.14)(9)³

9³ = 729

V = 4/3(3.14)(729)

729(3.14) = 2289.06

V = 4/3(2289.06)

Note: first multiply 4, then divide 3

2289.06(4) = 9156.24

9156.24/3 = 3052.08

your closest answer is A

hope this helps
