The rate at which fluid level inside vertical cylindrical tank of radius

r

drop if we pump fluid out at the rate of

3 \mathrm{~cm}^3 \mathrm{l} / \mathrm{min}

View answer and explanation

Correct option: B

\frac{3}{\pi r^2}

Option B (

\frac{3}{\pi r^2}

) is correct because it represents the rate of change of height with respect to time when fluid is pumped out at a given rate.
