A=v^2/r solve for v, solve for r

To rearrange these for v and r we must use BEDMAS.

First, times both sides by r, getting Ar = v²r/r
You can cancel out r/r to get Ar = v²

To get v, square root both sides. √Ar = √v²
Cancel out the square root and the squared v = √Ar

To get r, go back to Ar = v², then divide both sides by A. rA/A = v²/A
Then cancel out A/A to get r. r = v²/A

Iread this book last year so take this with a grain of salt.gene jumps from the tree to compete with finny due to the fact that gene is always trying to do better than finny. he is put under the grasp of peer pressure due to finny almost forcing him to do this. ever since he first jumped finny kept pressuring him to jump since he thought gene enjoyed jumping.rather than uses this answer you should probably just reread chapters 3-4
