.
The key idea of the solution is the fact that increase of the occupied volume is equal to the volume of the ball.
Keeping it in mind, we write this equation
= ,
where R is the unknown radius of the cylinder and r is the given radius of the ball.
From this equation
= = = ;
hence, R = = = 16 inches. ANSWER
