Depends if they want radians or degrees.
 Did I interfere a two-person thing?

You are such a gem! I took a quiz, and my teacher counted it wrong because I didn't know how to round 4 decimal points. Remember 4 to the floor, 5 to the sky. If the underlined number is lower than 4, keep it that number. If it's higher than 5, make it the next number.

I underlined 1 because it's the 4 number, and then I circled the 6. since the 6 is bigger than 5, I made the underlined number a 2 (next number after 1) 

If the circled number were a 2 for example, that's lower than 4 (4 to the floor), I would keep that underlined number, a 1.
