An office uses paper drinking cups in the shape of a cone, with dimensions as shown. to the nearest tenth of a cubic inch, what is the volume of each drinking cup?

The volume of a cone is given by the formula

If we plug in the known information into the formula, we will get the answer.

We know radius is half of d, so

The height is given as 4 in.

Pluggin all of these in the original formula gives us:

Rounded to the nearest tenth, our final answer is:

V=7.9 cubic inches

ANSWER

to the nearest tenth

EXPLANATION

The given cup has the shape of a cone with dimension,

and

The formula for calculating the area of a cone is given by;

Where r is the radius of the circular base.

We therefore divide the diameter in to two to find the radius.

This implies that,

We now plug in all the above in to the formula, to get,

to the nearest tenth
