Radius of Base of cone = 42 cm
Height of cone = 40 cm
Volume = pi *r^2 h /3
= 22*42*42*40/7*3
= 22 * 2* 42 * 40
= 44 * 42 * 40
= 73920 cm^3
Height of cone = 40 cm
Volume = pi *r^2 h /3
= 22*42*42*40/7*3
= 22 * 2* 42 * 40
= 44 * 42 * 40
= 73920 cm^3

Volume of cone = 1/3 X 22/7 X r^2 X h
Here, r = 42cm, h = 40cm
Volume of rt circular cone = 1/3 X 22/7 X 42 X 42 X40
=> 1 X 22 X 6 X 14 X 40 (As 42/7 = 6, 42/3 = 14)
Volume of cone = 73290 cm cube
Here, r = 42cm, h = 40cm
Volume of rt circular cone = 1/3 X 22/7 X 42 X 42 X40
=> 1 X 22 X 6 X 14 X 40 (As 42/7 = 6, 42/3 = 14)
Volume of cone = 73290 cm cube
