A cone of radius 10cm is divided into two parts by a plane parallel to its base through the mid-point of its height. Compare the volumes of the two parts

Volume of full cone = (1/3)10πr2 cm3

volume of top cone that has half of initial height = (1/3)(5/4)πr2 cm3 ......................(1)

( volume of top portion is calculated as above, because radius also half of its initial value)

volume of bottom portion = (1/3)πr2 [10 - (5/4)] = (1/3)πr2(35/4) cm3 .....................(2)

ratio of volume of top part of the cone to that of bottom part =
