How many gallons are in a cylinder 2ft tall and 30 in round if we take out 350 gallons?
:
1 cu/ft = 7.481 gal; 1728 cu/in = 1 cu/ft
:
Find the radius using the given circumference
2%2Api%2Ar = 30
r = 30%2F%282pi%29
r = 4.77 inches
:
Find the vol, Height = 24 inches
pi%2A4.77%5E2%2A24 = 1715.528 cu/inches
change to cubic ft, find no. of gal,
%281715.528%2F1728%29%2A7.481 = 7.427 gal, obviously you can't take out 350
