150 liters of water are poured into a cylinderical drum of diameter 48cm. find the depth of water in the drum
1L = 1000cm^3
So....150L = 150,000 cm ^3
Volume of cylinder = pi * (diameter/2)^2 *h =
150,000 = pi * (48/2)^2 * h
150,000 = pi * 24^2 * h =
150,000 = 576pi * h divide both sides by 576pi
[150,000] / [ 576pi ] = h = about 82.89 cm
