Solve S= pi symbol times r (h +k) for h

OpenStudy (imstuck):

is this your equation?\[S=\pi r(h+k)\]

OpenStudy (anonymous):

yes @IMStuck

OpenStudy (imstuck):

Ok, if I asked you to solve this for x, how would you do it? 3x = 6

OpenStudy (anonymous):

3x=6 so 6/3 so x =2 @IMstuck

OpenStudy (imstuck):

Ok, so you divided by the 3 to get the x alone, right? Do the same with the pi*r; treat it as if it were a constant. Divide it away from the (h+k). Show me.

OpenStudy (anonymous):

so s/pi*r = (h+k) ?

OpenStudy (imstuck):

Ok, it might be a bit easier to perceive if we remove the parenthesis. So let's do that. Here's what you have so far.\[\frac{ S }{ \pi r }=h+k\]

OpenStudy (imstuck):

How do you get rid of the k on the right?

OpenStudy (anonymous):

@IMStuck you subtract it from both sides right?

OpenStudy (imstuck):

yes you most certainly do! Do that and what do you get?

OpenStudy (anonymous):

S/pi*r - k = h

OpenStudy (imstuck):

That's correct! Very good!

OpenStudy (anonymous):

so that's the answer? @IMStuck

OpenStudy (imstuck):

Yes, that's the answer.

OpenStudy (anonymous):

@IMStuck oh my gosh! Thank you so so much! You made me understand how to do it!

OpenStudy (imstuck):

Youre so welcome! Glad to help!
