Explanation for Question 19 From the Math (No Calc) Section on the 2018 March Sat
Question 19 says an angle measure of 540 degrees was written and radiance 2 as X PI. What is the value of X? 3 So what we have to do here is take a degrees amount and then 4 translate that into an amount of radians. 5 So to do that, we're going to take our degree measure and multiply it 6 by PI over 180. That's how you convert a value from degrees to radians. 7 So 540 times PI over 8 180, and that just gives us three PI. 9 And so we know that the value of X is just equal to three. 10 And that's the correct answer here.
