![r over 20 equals h over 40
rightwards double arrow r equals 1 half h
A s space V equals 1 third πr squared straight h
straight V equals 1 over 12 πh cubed
rightwards double arrow dV over dt equals straight h squared over 4 straight pi dh over dt
rightwards double arrow dh over dt equals fraction numerator 1 over denominator 400 straight pi end fraction dV over dt](https://images.topperlearning.com/topper/tinymce/cache/b86df380cbb015ad5618f2a4034f7272.png)
