HELP OR THE PUPPY DIES solve for the variable r in this equation s=2πrh

OpenStudy (anonymous):

myininaya (myininaya):

undo the multiplication of the items being multiplied to r by dividing both sides by whatever that is

myininaya (myininaya):

example in solving the equation 5x=1 for x you would divide 5 on both sides

myininaya (myininaya):

so here what would you divide on both sides

myininaya (myininaya):

what is next to r

OpenStudy (anonymous):

i would do 5 also

myininaya (myininaya):

you don't have any 5's in your equation

myininaya (myininaya):

do you see anything being multiplied to r?

OpenStudy (anonymous):

nvm I got c i have no idea how but I know that is the correct answer

myininaya (myininaya):

do you see 2*pi*h next to r?

myininaya (myininaya):

2 pi h is the thing being multiplied to r

OpenStudy (anonymous):

yes

myininaya (myininaya):

that is the thing you divide both sides by

OpenStudy (anonymous):

thats what i did

myininaya (myininaya):

oh you said you didn't know how you got the answer...

OpenStudy (anonymous):

thats how?

OpenStudy (anonymous):

That's what I was doing this whole time even before I asked this question and-- ykw nvm sorry for wasting ur time medal!

myininaya (myininaya):

\[s= \text{ whatever} \cdot r \\ \text{ divide both sides by whatever } \\ \frac{s}{\text{whatever}}=r \]

myininaya (myininaya):

you didn't waste my time

myininaya (myininaya):

glad to help
