cylindrical standpipe is contain 343000 gal. of water. If its height is to be twice it diameter, what must be its dimension?
:
the vol of a cylinder:
h = twice the diameter which is 4 times the radius
therefore
= 342000
divide both sides by 4pi, resulting in
= 27295
find the cube root
r = 30.11
:
Diameter = 60.22
height: = 120.44
:
Check
= 343038 ~ 343000
