Calculations using Arc Lengths
and
Central Angles

arcCircle

The goal of this section is for you to learn about a concept in Geometry related to calculating the main dimensions related to every circle:

  • Circumference = ∏ x diameter
  • Diameter = 2 x radius
  • Radius = diameter ÷ 2
  • Arc Length = circumference x central angle ÷ 360°

    • Enter the Radius:

    The Diameter is:

    Enter the Diameter:

    Enter the Central Angle (in Degrees):

    The Arc Length is:
