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 cm^{3.}

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 * r^{2} * h

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

=> 19.404 cm^{3}

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 cm^{3}.

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

Solution:

Edge of the cube = 4.2 cm

Diameter of base of largest possible cone = 4.2 cm

∴ Radius = 4.2/2 = 2.1 cm

QUESTION: 9

In a swimming pool measuring 90 m x 40 m, 150 men take a dip. If the average displacement of water by a man is 8 m^{3}, then rise in water level is

Solution:

Volume of water displaced = 150 x 8 = 1200 m^{3}

⇒ 90 x 40 x h = 1200
