Answer:

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.
