A circular cylinder is 60 inches in height and has a volume of 30 gallons.
water is flowing into the cylinder at the rate of 5 gallons per minute.
At what rate is the level of water in the cylinder increasing?
:
30 gallons = 231*30 = 6930 cu/inches
:
Find the radius of the cylinder
pi*r^2*60 = 6930
=
= 36.7648
r =
r ~ 6.1 inches
:
Find the height (h) of a cylinder of 5 gallons of water
5 * 231 = 1155 cu/inches
:
= 1155
h =
h = 9.99 ~ 10 inches per minutes
