Q16 of 63 Page 20

If a cone is cut into two parts by a horizontal plane passing through the mid-point of its axis, the ratio of the volumes of upper and lower part is

We have, (by mid point theorem)


Radius of complete cone = 2r


Radius of small cone after cutting = r


Hight of complete cone = 2h


Hight of small cone = h






So ratio of volume of lower and upper parts =

If h, S and V denote respectively the height, curved surface area and volume of a right circular cone, then 3πVh3-S2h2+9V2 is equal to

If the heights of two cones are in the ratio of 1 : 4 and the radii of their bases are in the ratio 4 : 1, then the ratio of their volumes is
