What is the correct formula for arc length?
The formula for arc length is given by:
Arc length = (θ/360) * 2πr
where θ is the central angle (in degrees), r is the radius of the circle, and 2πr represents the circumference of the circle.
The formula for finding the arc length of a circle is:
Arc Length = (θ/360) * 2πr
Where:
- θ represents the central angle in degrees (or radians),
- r is the radius of the circle,
- 2πr represents the circumference of the circle.
So, to calculate the arc length, divide the central angle by 360 (or convert it to radians) and multiply the result by 2πr.
