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 $= 54\pi$

Due to hunting, the population of Northern elephant seals was reduced to 20 individuals at the end of the 19th century. Since th

anygoal [31]

Answer:

Option C

Explanation:

Long term hunting has led to following

a) Reduction in population size and hence the gene pool

b) Causation of Bottleneck effect

Due to above factors, the remaining population of Northern elephant seals does not represent the original genetic problem.

Due to this restriction in mating and genetic variation shall prevail pertaining to reduced gene pool.

Due to continuous hunting, the gene pool will further shrink, leading to genetic similarity among the organism

Option C is correct
