Question

Find the volume of a cone with a height of 9 centimeters and a radius of 5 centimeters.
Use 3.14 to approximate pi, round your answer to the nearest hundredth if necessary, and do not include units.

Answer 1

235.5

Explanation:

Substitute the values into the equation
`V=\pi r^2 (h)/(3)`, which is the formula for finding the volume of a cone.

`V=(3.14)(5^2)((9))/(3)`

Simplify.

`V=(3.14)(25)(3)`

Simplify again.

`V=(78.5)(3)`

Simplify for the last time.

`V=235.5`

Note, using 3.14 will give you 235.5, but if you use the
`\pi` button on a scientific calculator, your answer will be 235.62. Given the constraints of the problem, your best bet will be 235.5.
