Question

change 290 degrees to radian measure in terms of p.

Answer 1

A full circle = 2(pi) radians
Also, a full circle = 360 deg

That means that
2(pi) radians = 360 degrees

Divide both sides by 360 degrees:
2(pi radians / 360 degrees = 1

This ratio can be reduced to:
pi radians / 180 degrees = 1

Now you have a ratio of radians to degrees that equals 1.
Since multiplying a number by 1 does not change the number, multiply 290 degrees by 1, but with 1 written as (pi) radians / 180 degrees.

290 deg * (pi rad) / (180 deg) =
The degree units cancel out leaving radians.
Simplify the expression above for your answer.
