## Frequently Asked Questions

### What is the formula for length of an arc?

When the central angle is measured in degrees, the arc length formula is: When the central angle is in radians, the arc length formula is: θ indicates the central angle of the arc in radians.

### How do you find the angle subtended by an arc?

There is a relationship between the angle subtended by an arc in radians and the ratio of the length of the arc to the radius of the circle. In this case, θ = (the length of an arc) / (the radius of the circle). S = length of the arc. r = radius of the circle. One radian is the central angle subtended by an arc length of one radius, i.e., s = r

### How do you find the length of a 360 degree arc?

The radius and central angle Θ are the key components for determining the length of the arc. It is known that the arc length is equal to the circumference for an angle equal to 360 degrees or 2π radians. L / Θ = C / 2π.

### What is the measure of the angle of an arc?

The arc's angle measurement, taken at the center of the circle the arc is part of, is measured in degrees (or radians) Do not confuse either arc measurement (length or angle) with the straight-line distance of a chord connecting the two points of the arc on the circle.
