Convert the radian measure to degree measure. use the value of π found on a calculator, and round answers to two decimal places. 11 pi / 4

A full circle is 360 deg.
A full circle is 2 pi radians.

That gives us a conversion equation:

2 pi radians = 360 deg

which can be reduced to

pi radians = 180 deg

Divide both sides by pi radians to get

1 = (180 deg)(pi radians)

Now we can convert:

11 pi/4 radians * (180 deg)/(pi radians) = 11/4 * 180 deg = 495 deg
