Convert the angle 39° into radians. (Round to the nearest hundredth of a radian.)

Khan Academy Answer~ 0.68

The other options were,

0.44
0.46
None of the Above

I thought that the real answer should be "None of the Above."

39 degrees X pi/180 radians = 39/180

39/180 divided by 3 = 13/60

13 divided by 60 = 4.615

Round up 4.615 = 4.62

Please tell me how the answer turns out different
