Answer: I’m assuming you accidentally typed r a second time so.

c=2r, swap sides.
2r=c, divide both sides by 2.
r=1/2c, that should be your answer

Answer:

[tex] \sqrt{ \frac{c}{2} } = r[/tex]

Step-by-step explanation:

c=2rr

c = 2r×r

c= 2r²

c/2= r²

[tex] \sqrt{ \frac{c}{2} } = \sqrt{ {r}^{2} } \\ \\ \sqrt{ \frac{c}{2} } = r[/tex]
