What is the volume of this cone?
9.23 cu cm
9.42 cu cm
9.54 cu cm
9.87 cu cm

Given:

The radius of the cone is 2 cm.

The height of the cone is 2.25 cm.

We need to determine the volume of the cone.

Volume of the cone:

The volume of the cone can be determined using the formula,

where r is the radius and h is the height of the cone.

Substituting r = 2 and h = 2.25, we get;

Simplifying, we get;

Multiplying, we get;

Dividing, we get;

Thus, the volume of the cone is 9.42 cubic cm.

Hence, Option b is the correct answer.
