Question

relation between radion (rad) and angle

Answer 1

180 degree is π radians.

To convert x degree to radians multiply the x degree by (π/180).

X in radians = x*(π/180).

To convert y radians in degree multiply the y radians by (180/π).

Y in degree = y*(180/π).

Answer 2

thus,to radians equals 360° this means that /radian=180 degree =/180radian d(A,B)=Ra/180 these formulas can be checked by noticing that the arc length is proportional to the angle and then checking the formula for the full circle that is when a= 2Radian(or 360 degrees)
