Plug in values into the formula and see which combination gives you 60
OpenStudy (studygurl14):
60pi

ok let me try
OpenStudy (anonymous):
@StudyGurl14 could you give me like an example?
OpenStudy (studygurl14):
h = 10cm, r = 6 cm, d= 12 cm
\(\Large\frac{6^2\pi(10)}{3}\rightarrow \frac{36(10)\pi}{3}\rightarrow 12(10)\pi\rightarrow 120\pi\)
So, that doesn't work.
OpenStudy (studygurl14):
Remember, that the diamter must be 2 times the radius
OpenStudy (anonymous):
do we multiply?

@StudyGurl14 do we multiply?
OpenStudy (studygurl14):
what do you mean?
OpenStudy (anonymous):
how would i get it multiply them add what operation
OpenStudy (studygurl14):
The formula fro volume of cone is
\(\Large\frac{r^2\pi h}{3}\)
OpenStudy (anonymous):
d=18h=10r=9?
