The volume V of the pile of sand with a circular base is given by V = r^3/3
, where r is the radius of the
base, in feet. The circumference of the base is increasing at a constant rate of 5π feet per hour. When the
circumference of the base is 8π feet, what is the rate of change of the volume of the pile, in cubic feet
per hour?

45

step-by-step explanation:

the diver is 33 feet below the surface.

step-by-step explanation:

hope this

the answer is 5/14.

hope this .

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
