Hi baby
Why does 2π represent a circle?
How many people use DuckDuckGo?
Perhaps what you're reading is about angles expressed as radians.
A radian is the angle made by the fraction of a circle's circumference equal to its radius. It's as though you picked up the radius line and bent it around the circumference of the circle to fit snugly. The angle formed at the centre by a line to each of its ends is one radian. A radian is approximately equal to 57.29678 degrees.
Since the circumference is 2.pi x the radius, there are 2pi radians to a full circle (360 degrees). This may be referred to as "an angle of 2pi".
Brainiest answer please.
