Water drops into a graduated cylinder, of a diameter 10cm, at a rate of 20cm3/min. How high will the level have risen in 10 minutes
20 cm3 /min x 10 min = 200 cm3
Volume of cylinder = pi r2 h we are looking for h
200 cm^3 = pi 52 h solve for h ( remember it is r2 ....and you are given DIAMETER, r = 1/2 diameter = 5)
