Answer:
339π in³
Explanation:
The amount of water is the difference between the volume of the cylinder and the volume of the ball. The appropriate volume formulas are ...
cylinder V = πr²h
sphere V = (4/3)πr³
For the given numbers, the volumes are ...
cylinder V = π(5 in)²(15 in) = 375π in³
sphere V = (4/3)π(3 in)³ = 36π in³
The water volume is the difference of these ...
water volume = cylinder V - sphere V
= 375π in³ - 36π in³ = 339π in³
