A cylinder shaped water tank holds 200,000 gallons of water.
The height of the tank is 48ft.
To the nearest tenth of a foot, what is the radius of the tank?
:
Change 200,000 gal to cu/ft: .1337*200000 = 26740 cu/ft
:
Using the volume of a cylinder formula
= 26740
:
=
:
= 177.325
r =
r ~ 13.3 ~ 13 ft is the radius
:
:
Check this on a calc: (7.481 gal in one cu/ft)
; results: 199551 ~ 200,000
