There are three negative signs so the product will be a negative.

Line graphs (or line charts) are best when you want to show how the value of something changes over time, or compare how several things change over time relative to each other. Whenever you hear that key phrase “over time,” that's your clue to consider using a line graph for your data.

2pi radians in a circle
1 circle=360
therefor
ratio and proporiton
parts/whole=130/360=xradians/2pi
130/360=xradians/2pi
13/36=xradians/2pi
times 72pi both sides
26pi=36xradians
divide both sides by 36
(13pi)/18=xradians
(13pi)/18 radians
aprox 2.2689280275927 radians
