Question

A cone-shaped container has a height of 9 in. and diameter of 2 in. It is filled with a liquid that is worth $2 per cubic inch.

What is the total value of the liquid in the container?

Use 3.14 for π .

Enter your answer in the box.

Answer 1

If you would like to know the total value of the liquid in the container, you can calculate it using the following steps:

A cone:
a radius (r) ... 1 in.
a diameter ... 2 in.
a height (h) ... 9 in.
π ... 3.14

Cone volume formula:
V = 1/3 * π * r^2 * h
V = 1/3 * 3.14 * 1^2 * 9 = 1/3 * 3.14 * 1 * 9
V = 9.42 cubic inches

$2 ... 1 cubic inch
$x = ? ... 9.42 cubic inches
_______________________
2 * 9.42 = 1 * x
x = 2 * 9.42
x = $18.84

The correct result would be $18.84.
