Question

Tne circumference of the base of a right circular cone is 22 cm. If the height be 8 cm,
find the volume.​

Answer 1

2 pie r = 22 cm

2 X 22/7 X r = 22

r= 22X7/22X2=7/2=3.5 cm

Volume of Cone = 1/3 pie X r^2 H

V= 1/3 X 22/7 X 7/2 X 7/2 X 8

V= 77 X4/3

V (approx.) = 102.6666666666667‬  cubic centimeters
