Convert 3 radian in to degree measure |
| Answer» To convert radian into degrees, the value of radian is multiplied with 180/pi. So,3 radian= (3×180/pi)°=171 9/11°We cannot leave the value of degree in mixed fraction. So we have to convert the mixed fraction into sub units of degree- minutes(\')and seconds("). We will take 9/11° and convert it into min. So,9/11°=(9/11 × 60)\'=49 1/11\'Now we will change 1/11\' into seconds. So,1/11\'=(1/11 × 60)"=5.45 secondsWe cannot leave the value of seconds in mixed fraction. We have to write it in decimal form if the number is not exactly divisible.The whole answer,3 radians= 171°49\'5.45"Hope this helps. | |
