Question

Solve the formula for h.
(Formula below)

Answer 1

\[S = 2 \pi rh + 2 \pi r ^{2}\]

Answer 2

Hey rmaker, I hope I'm not just doing your homework for you! You should treat the other variables like they are numbers, and then solve like you're doing algebra.

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

Subtract the term that doesn't have h in it from both sides

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

Divide away everything that isn't h from both sides


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

Answer 3

@cholo71796 you are a godsend. (actually you are helping me with my homework. I haven't ate anything since lunch so my brain doesn't work that well.)

Answer 4

Eating is important! I hope my explanations are making sense though and you're not just writing down my answers!

Answer 5

not my specialty

Answer 6

@cholo71796 well, i'm doing both. Thanks for all the help!!

Answer 7

@cholo71796 sorry, last question. would the simplified form of (S - 2pi*r^2)/(2pi * r) = h be S - pi * r = h?

Answer 8

No, the simplified form is

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

Answer 9

can't you simplify it even more?

Answer 10

Not really, you can split it into separate fractions if you'd like

S/(2*pi*r) - (2*pi*r^2)/(2*pi*r)

which is the same as

S/(2*pi*r) - r

which is kind of neater but it's not any more simplified

Answer 11

ok thanks!
