Arc Length Calculator





Formula

The formula to calculate the total length of an arc is:

\[ L = r \times \Theta \]

where \( L \) is the arc length, \( r \) is the radius, and \( \Theta \) is the central angle or angle of rotation in radians.

What is Arc Length?

The arc length is the distance along the curved line making up the arc. It is a portion of the circumference of a circle. The arc length can be calculated by multiplying the radius of the circle by the angle of rotation in radians.

Example Calculation

Let's assume we have the following values:

Step 1: Multiply the radius by the angle of rotation:

\[ L = 5 \times 2 = 10 \text{ units} \]

Therefore, the total arc length is \( L = 10 \) units.
