## anonymous 5 years ago 215=1/3pi*x^2*13.. solve for x

1. anonymous

are you allowed to use a calculator for this problem?

2. anonymous

yeah do you need a graph or the result of x?

3. anonymous

i just need to find the value of x... its for the volume of a cone

4. anonymous

$X=\sqrt{645/13\pi}$

5. anonymous

yay! i figured out the equations button!

6. anonymous

x is the radius of the cone

7. anonymous

thats a really gross equation because that's as simplified as it gets...

8. anonymous

this is correct

9. anonymous

so i dont do 13*pi/3=(13.61)x^2= 215/13.61=15.80

10. anonymous

$so using x =\sqrt{645/13\pi }$ i got 12.48
