Unformatted text preview: 8 cm 3000 m = 3000 m (100 cm)/(1 m) = 3 10 5 cm The volume of the half cylinder is given by the area of semicircle times height. Thus we get V = (r 2 /2) h = [3.14 (2 10 8 )2/2] 3 10 5 = 1.88 10 22 cm 3 b) How many cubic feet of ice does Antarctica contain? (1 ft = 30.48 cm) We already have the volume in cm 3 , so all we have to do is to convert it to ft 3 . Since the original unit has cm in numerator, we multiply the conversion factor which has cm in the denominator so that they cancel. We multiply the factor three times. We have V = 1.88 10 22 cm 3 (1 ft/30.48 cm) 3 = 6.64 10 17 ft 3...
