Question

s=2πr^2+2πrh solve for h
step by step please =]

Answer 1

s-2pi r^2=2pirh
h=(s-2pi r^2)/2pi r

Answer 2

I'll add some words.

Given that

s = 2*pi*r^2 + 2*pi*r*h

subtract the term that does not contain h on the right hand side and add it to the left

s - 2*pi*r^2 = 2*pi*r*h

Divide by the 2*pi*r on both sides to get

(s - 2*pi*r^2)/(2*pi*r) = h

Answer 3

Or rather,
"subtract the term that does not contain h on the right hand side and add it to the left"
should be
"subtract the term that does not contain h on the right hand side and subtract it from the left",
sorry brain dead there
