Check the picture below.
let's recall that 2π is a full go-around or namely a revolution

It should be 34/5*. If you create an improper fraction out of the original one, then creating the reciprocal will be easier.
B=48/7 you simplify 7/b(b) to 7b/6
Then multiply both sides by 6 so 8 x 6 =7b then simplify 8 x 6 =48
And divide both sides by 7 48\7 then switch sides b=48/7
