Express h in terms of pi,r and s,

Can someone show me how to transpose this in terms of h

s = pi r (r + 2h)

Thanks...Mark

Re: Express h in terms of pi,r and s,

s = πr (r+2h)

s/πr = r+2h

s/πr - r = 2h

(s/πr - r)/2 = h

Why did the vector cross the road?
It wanted to be normal.

Hi,
Thanks for the reply.

Is that the same as h = s-pi r2/2pi r

getting confused

Hi manich44;

Yes , it is the same as:

Yes, that's probably a better way of expressing it.
Sorry, I was in a rush before.
