To convert degree measure to radian measure we have to use the formula given below. The total angle of a circle equals 360 or we can call it as 2 radians. We represent the angle between two lines through radians and degrees.
We convert p9 radians into its corresponding degree value.
Put the 40 in place of the first numerator in the proportion. Using the formula 330 x p180. Degrees to radians conversion formula. Multiply each side of the proportion by pi.
