How to solve circumference with radius
WebTo find the arc length, we definitely need the radius of the circle and central angle. But when the radius is not given, then either the sector area or the chord length might have been given. Use the following formulas to solve for the radius and then apply the arc length formula. Sector area = (θ/360º) × πr 2, if θ is in degrees (or) (1/2 ... WebFor example, let us draw a chord of length 4 inches in a circle that has a radius of 2 inches. Mark the center of the circle as O and using a compass draw a circle with a radius of 2 inches. Then, mark a point C on the circumference of the circle, and with C as the center draw an arc that cuts the circumference at another point D.
