L r th 15 p4 1178 cm. Example 1 Find the arc length and area of a sector of a circle of radius 6 6 cm and the centre angle 2p 5 2 p 5. Divide by 360 to find the arc length for one degree.
Enter central angle 638 then click CALCULATE and your answer is Arc Length 40087.
We can also use the angle measure to help us find the arc length. Calculate the arc length according to the formula above. You can also use the arc length calculator to find the central angle or the circles radius.
