Explanation: 1- getting the radius before the ball is fully inflated: volume of sphere =
We are given that the volume before the ball is fully inflated is 180 in³. Therefore, we can solve for the radius as follows: 180 = 135 = π * r³ 42.9718 = r³ radius = 3.5026 in
2- getting the radius after the ball is fully inflated: volume of sphere =
We are given that the volume after the ball is fully inflated is 294 in³. Therefore, we can solve for the radius as follows: 294 = 220.5 = π * r³ 70.187 = r³ radius = 4.124958 in
3- getting the increase in the radius: increase in radius = radius after inflation - radius before inflation increase in radius = 4.124958 - 3.5026 increase in radius = 0.622 which is approximately 0.6 in
