WebR is the radius of the arc π is Pi, approximately 3.142 Recall that 2πR is the circumference of the whole circle, so the formula simply reduces this by the ratio of the arc angle to a full angle (360). By transposing the above formula, you solve for the radius, central angle, or arc length if you know any two of them. A circular arc is the arc of a circle between a pair of distinct points. If the two points are not directly opposite each other, one of these arcs, the minor arc, subtends an angle at the centre of the circle that is less than π radians (180 degrees); and the other arc, the major arc, subtends an angle greater than π radians.
