myininaya (myininaya):

\[(x-h)^2+(y-k)^2=r^2\] (h,k) is center r is radius

myininaya (myininaya):

\[(x-1)^2+(y+\frac{3}{2})^2=\frac{9}{4}\] \[(x-1)^2+(y-\frac{-3}{2})^2=\frac{9}{4}\] \[\text{ So what is } h?\] \[\text{ what is } k? \] \[\text{ what is } r^2? \]

myininaya (myininaya):

\[\text{ Once we find } r^2 , r \text{ can be found by talking square root of both sides }\] But don't forget r is positive :)

81/16?

myininaya (myininaya):

Tell me what \[r^2\] is ?

myininaya (myininaya):

Like \[r^2\] is in the place of where that 9/4 is So \[r^2=\frac{9}{4}\] How did I say to solve this for r?

OpenStudy (anonymous):

uh idk

myininaya (myininaya):

I said r can be found by taking square root of both sides Don't forget r is positive

OpenStudy (anonymous):

idk why i can't think T.T so both sides of the equal sign?

mk ima guess it's the second to last
