Question

Water flows into a vertical cylindrical tank at the rate of 24 cubic ft per minute. If the radius of the tank is 4 ft, how fast is the surface rising?​

Answer 1

24 / 50.24 = 0.48 feet per minute

so the answer to your question is 0.48 feet per minute.

hope this helps you

Answer 2

given:

per min= 24 cubic ft

radius= 4 ft

to find:

how fast the surface rises.

solution:

`area = \pi {r}^(2)`

`a = \pi * {4}^(2)`

`a = 50.24 \: {ft}^(2)`

`v = 24 \: {ft}^(3)`

`= (24)/(50.24)`

`= 0.48`

therefore, the rising in the surface area is 0.48 feet per minute.
