D. 8.8 cm^3
Step-by-step explanation:
The formula for the volume of a cone is...
[tex]V=\frac{1}{3}\pi r^2h[/tex]
We can plug everything we know into the formula and convert pi to 3.14 since the answer choices aren't in pi.
[tex]V=\frac{1}{3}*( 3.14*1.45*1.45*4 )[/tex]
I prefer to do the 1/3 last, but it is entirely up to you!
Now solve...
[tex]V=\frac{1}{3}*26.4074[/tex]
Divide by 3.
V =
8.8 cm^3
