Question

A CONE OF MAXIMUM SIZE IS CARVED OUT OF A CUBE OF EDGE 21cm . FIND THE VOLUME OF THE CONE .......

Answer 1

From the given data, the height of the cone is 4.2 cm and the radius of the cone is 4.2/2 cm i.e. 2.1 cm

therefore, the volume of cone = pi x r2h

= 22/7 x 2.1 x 2.1 x 4.2 cm3

= 58.212 cm3

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