To solve this problem, we have to understand and establish some basic mathematical facts on a cone.
The answer to this question are option b and c only.
<h3>Cone</h3>
This is a solid figure that has the base of a circle and the top is made up round triangle.
The formula of volume of a cone is given as
where;
In the given question, the first fact given is if the radius doubles the diameter and that false.
If we have the value of the the radius, we can calculated the base area using area of a circle
The volume of a cone is actually one-third the volume of a cylinder
we can only calculate the volume of the cone is we have the value of the height of the cone.
The answer to this question are option b and c only.
