Please tell me how to solve below question

A circular rain puddle is evaporating (losing water) at 5 cm³ per minute. When the puddle is 1/4 cm deep, the radius is 30cm and the radius is shrinking at a rate of 0.01 cm per minute. How fast is the height of the puddle shrinking at that point in time?

Write down all work. You will be asked to upload it in the next question.

Enter your answer as a positive number in cm per minute. Round your answer to 4 decimal places.
