Answer:
1: 3 ratio of the volume of the cone to the volume of the cylinder
Step-by-step explanation:
Volume of cone(V) is given by:

where, r is the radius and h is the height of the cone.
Volume of cylinder(V') is given by:

where, r' is the radius and h' is the height of the cylinder.
As per the statement:
A cylinder and a cone have congruent heights and radii.
⇒r = r' and h = h'
then;

⇒
Therefore, the ratio of the volume of the cone to the volume of the cylinder is, 1 : 3
37 would be the answer.....
