Radian is the length of an arc of a unit circle that is numerically equal to the measurement in radians of the angle. Convert Radians. WebRadius of Circle Equation. The radius of a circle equation on the cartesian plane with center (h, k) is given as (x − h) 2 + (y − k) 2 = r 2. This is known as the equation of a circle when the radius is known. Here, (x, y) are the points on the circumference of the circle that is at a distance ‘r’ (radius) from the center (h, k).

WebSteps. Step 1: Plug the angle value, in degrees, in the formula above: radian measure = (360 × π)/180. Step 2: Rearrange the terms: radian measure = π × 360/180. Step 3: Reduce or simplify the fraction of π if necessary. Calculating the gcd of 360 and 180 [gcd (360,180)], we've found that it equals 180. So, we can simplify this fraction by ...
