Question

the radius of the base of a right circular cone os 12dm and the slant height is 150cm .find its volume .​

Answer 1

Step-by-step explanation:

formula for volume of right circular cone is

(πr^2h)/3

here radius = 12dm slant height = 150/10 cm=15 dm

so it's height = V(225-144)=✓81=9

volume=πr^2(h/3)=π(144)(15/3) =π(48)(15) =720 cm^3
