The key to solve this problem is to find out where the circular arc radius and central angle degree Then, by the arc length formula for the arc length. Then the two exercises is to grasp the situation to test students knowledge learnt on the front of the students. In the process of ...
divide the curve into small segments and then find the straight-line distance between each segment’s endpoints. Finally, add up all of those distances to get an approximation for the total arc length.

What is the formula for arc length of a sector? The formula to find the arc length of a sector is as follows: {eq}s=r\theta {/eq}, where you would need the length of the radius between the endpoint of the arc and the center of the circle, and the angle's measure in radians....
What is the formula for the length of an arc? If the subtended angle is given in radians, the formula for arc length is s=r*theta, where "s" is the arc length, "r" is the radius of the circle, and "theta" is the subtended angle. If the angle is instead given in degrees, the...
