ARC

Introduction to Arc Length

Calculating the length of an arc is a fundamental concept in geometry and trigonometry. An arc is a portion of a curve, typically a segment of a circle. Whether you’re working on a math problem or designing something in real life, determining the length of an arc is a valuable skill. In this article, we’ll introduce you to an ARC Length Calculator and explain how it works.

Understanding Arc Length

Before we dive into the calculator, let’s understand the components involved in calculating the length of an arc:

  • Radius (r): This is the distance from the center of the circle to the starting point of the arc.
  • Angle (θ): The angle formed at the center of the circle by the arc. It is typically measured in degrees.
  • Arc Length (L): The length of the arc you want to calculate.

The formula to calculate the arc length is:

�=�360×2��

Where:

  • is the arc length.
  • is the central angle in degrees.
  • is the radius of the circle.
  • (pi) is approximately equal to 3.14159.
