Well, darling, the formula for circumference is 2πr, so we can solve for the radius by dividing the circumference by 2π. That gives us a radius of approximately 2.7 mm when rounded to the nearest tenth. Hope that clears things up for you, sweetie!
By definition, the number of radians in one complete revolution is given by the ratio of the circumference of a circle to its radius. The circumference of a circle of radius r is of length 2πr. There are thus 2πr/r = 2π radians in one revolution. So, 2π radians = 360° Then 1 radian = 360/2π = 57.296° or 57° 17'
