Answer:

235.5

Step-by-step explanation:

Substitute the values into the equation [tex]V=\pi r^2 \frac{h}{3}[/tex], which is the formula for finding the volume of a cone.

[tex]V=(3.14)(5^2)\frac{(9)}{3}[/tex]

Simplify.

[tex]V=(3.14)(25)(3)[/tex]

Simplify again.

[tex]V=(78.5)(3)[/tex]

Simplify for the last time.

[tex]V=235.5[/tex]

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