WebOne radian is the angle measure that we turn to travel one radius length around the circumference of a circle. So radians are the constant of proportionality between an arc length and the radius length. It takes 2\pi 2π radians (a little more than 6 6 radians) to make a complete turn about the center of a circle.
WebWhen the diameter of a circle is known, the formula is, Radius = Diameter/ 2. For example, if the diameter is given as 24 units, then the radius is 24/2 = 12 units.
