is this right??

Question

is 3/4 pie radians converted to degrees ..45 degrees?

and

210 degrees converted to radians ..is 7/6 pie or 5/4pie ??

and

1/24 expressed to 4 places is 0.4167 ?

Answer 1

3/4pie is 135 degrees , to find this you multiply 3*180 and then divide theanswer by four.
210 degrees is = to 7pie/6 to find this you multiply 210*pie over 180, and then you just simplify

1/24=0.0417

Answer 2

2pi is converted to 360 degrees.

pi/4=2pi/8 is converted to 360/8=45 degrees

3pi/4 is converted to 3*45=135 degrees.

210*pi/180 = 21pi/18 = (7/6) pi

1/24 = 0 remainder 1 multiply 1 by 10

1st after the point) 10/24 = 0 remainder 10
2nd after the point) 100/24 = (96 + 4)/24 = 4 remainder 4
3rd after the point) 40/24 = 1 remainder 16
4th after the point) = 160/24 = 6 remainder 16

Because 16>24/2 = 12, we add 1 to the 4th digit after the point when rounding, and write it this way:
0.0417

Answer 3

To convert from radians to degrees, multiply by 180/pi

Likewise, the other way around is pi/180
