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 ... WebGiven, Radius of the circle = 28 cm. To find the circumference of the circle, we will use the circumference formula: 2πr = 2 × 22/7 × 28 = 176 cm. Therefore, the circumference of the circle is 176 cms. Example 2: The circumference of a …
