Find the volume of a right circular cone that has a height of 8.1 in and a base with a diameter of 7.6 in. Round your answer to the nearest tenth of cubic inch

Step-by-step explanation:

The volume of a right circular cone is given by:

where r is the radius of the circle and h is the height of the cone, and is a constant .

According to the problem the height is:

and we don't have the radius but we have the diameter, which is useful to find it. We just divide the diameter by 2 to find the radius:

Now, we can find the volume by substituting all the known values:

Rounding the volume to the nearest tenth of cubic inch we get:
