<span>Silicon dioxide forms the cell walls of diatoms. These diatoms are a group of algae. Phytoplanktons are the most common types of diatoms that are unicellular. These organisms can form colonies in the shapes of filaments or ribbons, fans, zigzags, and stars that are perfect for monitoring environmental conditions, particularly water quality in the past and present. </span>

A sand storage tank used by the highway department for winter storms is leaking. As the sand leaks out, it forms a conical pile.

harina [27]

Answer:

Rate of change of volume of the pile $= 54\pi$

Explanation:

Given -

Rate of increase of the base of the pile $= 0.75$ inches per minute

Height of the pile $= 2 *$ the radius of the base

Let "h" be the height of the pile and "r" be the radius of the base.

Then $h = 2* r$

Radius "r" $= 6$ inches

Rate of change of radius i.e

$\frac{dr}{dt} = 0.75$

Volume of conical pile

$\frac{\pi }{3} * r^2 * h\\= \frac{\pi }{3} * r^2 * 2 * r\\= \frac{\pi }{3} *2* r^3$

Change in volume of conical pile

$\frac{dV}{dt} = \frac{dr}{dt} * \frac{6* \pi * r^2 }{3}$

Substituting the value of rate of change of radius, we get -

$\frac{dV}{dt} = 2 * \pi * (6^2) * (0.75)\\\frac{dV}{dt} = 54 \pi$

Rate of change of volume of the pile $= 54\pi$
