A hot water tank is in the shape of a right circular cylinder surmounted by a hemisphere. How many gallons does the tank hold? ( 1.00 ft^3 contains 7.48).
H= 4.75ft
Diameter= 2.50 ft
------------
radius = 1.25 ft
If the 4.75 ht includes the hemisphere, then the height of the cylinder = 3.5 ft
---------
Cyl vol = cf
The hemisphere vol =
Total = 6.7708*pi cf
=~ 159 gallons
