Answer: 256 inch ^ 3
Explanation:
They gave you the formula to solve it
V = 4/3 (3) R ^ 3 /// You already have the radius, just plug it in the formula.
V = 4/3 (3) 4 ^ 3
V = 4/3 (3) 64
V = 4/3 193
V = 256
The answer is 256 inch ^3
Normally Pi is 3.14 in its simplified form but it tells you to use 3 in this situation.
