Question

Given the following formula, solve for r c=2rr

Answer 1

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 2

`\sqrt{ (c)/(2) } = r`

Explanation:

c=2rr

c = 2r×r

c= 2r²

c/2= r²

`\sqrt{ (c)/(2) } = \sqrt{ {r}^(2) } \\ \\ \sqrt{ (c)/(2) } = r`
