Let A 80 degree radians Enter an exact expression using p

Let A = 80 degree = radians. (Enter an exact expression using p to denote pi) Let B = pi/5 = degrees. In this problem you are asked to convert radians to degrees. In this problem you are asked to convert radians to degrees. 6 pi rad = degree. 0.7 rad = degree. (squareroot 2) pi rad = degree. 360 degree = 2 pi ~ rad.

Solution

To convert a degree to radian we have to multiply the degree by pi/180

80 degree= 80pi/180= 4pi/9 radian

To convert radian to degree we have to multiply it by 180/pi

pi/5 radian=pi/5*180/pi=36 degree

6pi radian= 6pi*180/pi=1080degree

sqrt2 pi radian= sqrt2 pi*180/pi=180sqrt2 degree
