How many degrees are a circle
WebCounterclockwise rotations about the center point where a complete rotation corresponds to an angle of rotation of 1 turn. A turn is a unit of plane angle measurement equal to 2π radians, 360 degrees or 400 gradians . Subdivisions of a turn include half-turns, quarter-turns, centiturns, milliturns, etc. Web2 pi radians is 360 degrees, so yes, all circles have an angle of 2 pi. In this video however, Sal is talking about the length of the circumference or a fraction of the circumference. This value will depend on the size of the circle. 7 comments ( 140 votes) Upvote Downvote Flag more Show more... Amol 10 years ago What does subtends mean •
