Answer:
Rate of increase in height =
Step-by-step explanation:
we know that volume of a cone is given by

It is Given that diameter equals height thus we have

Differentiating both sides with respect to time we get

Applying values and solving for
we get

Hey! I'll provide you the answers!
First you want to simplify the equation using cross-multiplication.

Finally, you would want to divide both sides by 15.
n = 161
