## anonymous one year ago how to solve for pi in SA=2*pi*r^2+2*pi*r*h

1. DanJS

you want to solve that for pi ?

2. anonymous

yeah its a manipulation of equations

3. DanJS

ok....

4. DanJS

really all you have to do is factor the pi out of both terms on the right side, then divide the SA by all that stuff that is left

5. anonymous

but how do i factor out pi on both sides

6. DanJS

$SA = \pi *[~2r^2 + 2rh~]$

7. anonymous

ohh

8. DanJS

yeah , then divide both sides by all tha tin the bra kets

9. anonymous

ok thank you

10. DanJS

$\pi = \frac{ SA }{ 2r^2+2rh }$ for right circular cylinder... welcome
