The diameter of a right circular cone is 14 m, while its slant height is 9 m, Find the volume of the cone.?
Correct Answer: 49 π √32/3 m3
Explanation:
Given, l = 9 m
and diameter = 14 m ⇒ r = 14/2 = 7 m
Now, volume = (1/3)πr2h
= (1/3)π x 49 x √l2 - r2
= (1/3)π x 49 x √81 - 49
= (1/3) x 49π x √32 = 49π√32 /3 m3
