Question
The ratio of the radii of the bases of a cylinder and a
cone is 5:6, while the ratio of their heights is 3:4. What is the ratio of the volume of the cylinder to the volume of the cone?Solution
ATQ,
Let r and R be the radii of the bases of the cylinder and the cone, respectively. r/R =5/6 Let h and H be the heights of the cylinder and the cone, respectively. h/H =3/4 The formula for volume ratio: 
Substituting values: 
Hence, the ratio of the volumes is 25:16.
