QUESTION: 5

The volume of the largest right circular cone that can be cut out from a cube of edge 4.2 cm is

Solution:

The volume of the largest right circular cone that can be cut out from a cube of edge 4.2 cm is 19.404 cm3.


Edge of the cube = 4.2 cm

i.e 2r = 4.2

r = 4.2/2 = 2.1 cm

h = 4.2 cm

Volume of the cone = 1/3 * pi * r2 * h

=> 1/3 * 22/7 * 2.1 * 2.1 * 4.2

=> 19.404 cm3

Hence, the volume of the largest right circular cone that can be cut out from a cube of edge 4.2 cm is 19.404 cm3.

QUESTION: 6

The radius (in cm) of the largest right circular cone that can be cut out from a cube of edge 4.2 cm is
