Answer:

V = \frac{4}{3}π units^3

Step-by-step explanation:

The formula for the volume of a sphere is:

V = 4π\frac{r^{3} }{3}

Now, substitute 1 for r because the radius is 1:

V = 4π\frac{1^{3} }{3}

Next, simplify the fraction:

V = \frac{1}{3}(4π)

Finally, multiply \frac{1}{3} by 4π:

V = \frac{4}{3}π

Gravel is being dumped from a conveyor belt at a rate of 15 ft3/min, and its coarseness is such that it forms a pile in the shap
gayaneshka [121]

Answer:

0.13 ft/min

Step-by-step explanation:

We are given that

\frac{dV}{dt}=15ft^3/min

We have to find the increasing rate of change of height of pile  when the pile is 12 ft high.

Let d be the diameter of pile

Height of pile=h

d=h

Radius of pile,r=\frac{d}{2}=\frac{h}{2}

Volume of pile=\frac{1}{3}\pi r^2 h=\frac{1}{12}\pi h^3

\frac{dV}{dt}=\frac{1}{4}\pi h^2\frac{dh}{dt}

h=12 ft

Substitute the values

15=\frac{1}{4}\pi(12)^2\frac{dh}{dt}

\frac{dh}{dt}=\frac{15\times 4}{\pi(12)^2}

\frac{dh}{dt}=0.13ft/min
