Arc Length of a circle is distance between 2 end points of arc. Arc is the part of circumference of a circle, as shown below.
How will you calculate the arc length of a circle having radius 6 cm and central angle 50 degrees?
Radius of the arc (r) = 6 Central angle (Θ) = 50
Arc length of a circle.
Let us learn to calculate the value of Length of arc Substitute the values in the formula, Arc Length of a Circle (S) = 2 x π x r (Θ / 360) = 2 x (22/7) x 6 x (50 / 360) = 2 x 3.143 x 6 x 0.139 = 5.2425
