Change `4pi ` to degree measure.
Multiply radians by `(180˚)/pi ` to convert to degrees.
Therefore, ` 4pi ` `*` `180/pi ` .
`pi` cancels which leaves 4 `*` 180 = 720.
`4pi `=720˚

We know that the conversion factor is pi radians = 180 degrees. Since we are given the measure in radians we will multipliy by 180 degrees / pi radians so that units and pi cancels properly.
4pi x 180/pi = 720 degrees.
