Answer:
Explanation:
In order for the ratio of volumes of a cylinder, cone, and sphere to be true, the radius of each solid would have to be equal. This is because the radius is a factor in the volume formulas for all three solids:
Volume of cylinder: πr^2h
Volume of cone: (1/3)πr^2h
Volume of sphere: (4/3)πr^3
If the radius is equal in all three solids, then the volumes will be in the same ratio as the given ratio, regardless of the values of h or the surface area. Therefore, the correct answer is : The radius and the height.
