Question

Which statements about the cone are true? check all that apply. the radius is double the diameter. the radius is 9 mm. the base area is calculated using the radius. the volume is one-third the volume of a cylinder with the same height and diameter. the volume of the cone is 297 pi millimeters cubed.

Answer 1

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.

Cone

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

$v = \frac{1}{3}\pi r^2 h$

where;

• r = radius
• h = height

In the given question, the first fact given is if the radius doubles the diameter and that false.

$diameter = 2 * radius$

If we have the value of the the radius, we can calculated the base area using area of a circle

$area = \pi r^2$

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.
