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

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.

b segment jm is correct i think
