to convert from radians to degrees, multiply by the conversion factor 180°/π. So 7π/5 * 180°/π = 252°

There are 2 pi radians in 360 degrees. I use the value of pi = 3.1416 (rounded to nearest 0.0001) Using proportions: It is difficult to show fractions in this format but the reader should visualize the proportion below as a set of fractions with numerator and denominator. 2 times 3.1416 radians divided by 360 degrees equals Unknown # of radians divided by 125 degrees Therefore, the unknown number of radians equals (6.2832 times 125) divided by 360 equals 2.1817 radians. Noting that I had not addressed the "revolution" part of your question, I feel that what is requested is the fractional or decimal portion of the 125 degree angle to a full revolution. If so, 125 degrees divided by 360 degrees (1 full revolution) is equal to 125/360 = 25/72 of a full revolution = 0.3472 of a full revolution.

pi radians = 180 degrees
7pi/5 radians = 7*180/5 = 252 degrees

to change from radian to degree, multiply by 180/pi
(7pi/5) * (180/pi) = 252 degrees

pi radians = 180°
((7pi/5)/ pi) * 180° = 252°

7pi /5 rad
= (7pi / 5) *(180/pi)
=(180*7)/5
=252 degree#

180 deg = pi radians
So, 1 rad = 180/pi degrees
So, 7pi/5 rad = 7pi/5 180/pi deg
= 252 deg

252º
this is because 180 º is equivalent to π in radians
so (7π/5)*(180/π)
=252 º

π radians=180º so
7π/5=180º/π=252º
