A cylindrical tank holds 11,550 in3 of water. Iha empties the tank into 25 smaller identical cylinders, each with a radius of 2.71 in.

What is the height of the 25 smaller cylinders? Use 3.14 to approximate pi and round the answer to two decimal places.

hmmm how did  you get 20.03 anyway?

do you happen to recall the volume of a cylinder's formula?

welshfella · Answer

the volume of water in the big tank = volume water in  25 of small cylinders
so if we let the height of the small ones be h we have:

volume of cylinder = 3.14*r^2* h

11,550 = 25 * 3.14*2.71^2 * h

h = 11,550 / (25*3.14*2.71^2)
