One cone has a height of 3cm with a volume of 216cm³. The other cone has a height of 7cm. What is the volume?

Answer 1

Volume of cone(V) = (1/3)*π*r²*h

Considering the radii of both cones are same. (Since in the question they have to mention about radius too, if they haven't we have to consider as same)

V is proportional to h

=> (v1/v2) = (h1/h2)

(216/v2) = (3/7)

volume of 2nd cone(v2) = 504

Answer 2

Are the radii the same?
