A right circular cylinder has a diameter of 12 in and a height of 12 in. if water is flowing in at the rate of 4π in3 per minute

The rate of change of the height is $\frac{1}{9}$ in/min.

<h3>What is a right circular cylinder?</h3>

A right circular cylinder is a cylinder that has a closed circular surface having two parallel bases on both the ends and whose elements are perpendicular to its base. It is also called a right cylinder.

Volume of the cylinder = $\pi r^{2}h$

Rate of change of height is $\frac{dh}{dt}$ = ?

At any time t,

Volume, V = $\pi r^{2}h$

Since r does not change with time, then r is a constant, so,

V = $\pi (6)^{2}h$

V = $36\pi h$

Differentiate both sides with respect to time t,

$\frac{dV}{dt} = 36\pi \frac{dh}{dt}$ -------------(i)

Since $\frac{dV}{dt}$ is given as 4 $\pi$ cu.in. per min,

$4\pi = 36\pi \frac{dh}{dt}$

$\frac{dh}{dt} = \frac{4\pi }{36\pi }$

$\frac{dh}{dt} = \frac{1 }{9 }$ in/min.

Hence, The rate of change of the height is $\frac{1}{9}$ in/min.
