Question

Find the volume of a cone if radius of its base is 7 cm and its perpendicular height is 15 cm.

Answer 1

The radius of base of the cone (r) = 7 cm

Its perpendicular height (h) = 15 cm.

Volume of the cone = `1/3 πr^2h`

= `1/3 xx 22/7 xx 7^2 xx 15`

= `1/3 xx 22/7 xx 7 xx 7 xx 15`

= `1/3 xx 22 xx 35`

= 770 cm³

The volume of the cone is 770 cm³.
