Question

A cylinder of diameter 12cm and unknown height is filled with water. The cylinder starts
leaking, and the height of water in this cylinder decreases by 0.5cm per minute. What is the
rate at which the volume of water is leaking from the cylinder, in centimetres cubed per
minute, when the level of water is down to 4cm? ?
Hint: The volume, V. of a cylinder of radius r and height his V = πr^2h.​
