Short answer 3 times as much = 54 m^3 <<<<< answer
The volumes are krelated by k So solve for k
Volume of Cylinder = k Volume of the cone.
pi r^2 h = k(1/3 pi r^2 h) Since you know that r is the same in both and so is h they divide out.
divide by h
pi r^2 = k (1/3 pi r^2 Divide by pi
r^2 = k (1/3 r^2 ) Divide by r^2
1 = k (1/3) multiply by 3
3 = k
The volume will be 3 times as much.as the cone.
3 * 18 = volume of cylinder.
54 <<<< volume of cylinder.
