Radius is 10 cm
circle circumference = 2 * PI * 10
circle circumference = 62.8
Arc is (20/360) of the circle
Arc = (20/360) * 62.8 = 3.4888 cm

Length of Arc is 3.5 cm Approx.

Given that;

Radius of circle = 10 cm

Angle = 20°

Find:

Length of Arc

Computation:

Length of Arc = [θ / 360]2πr

Length of Arc = [20 / 360](2)(3.14)(10)

Length of Arc = [0.055][62.8]

Length of Arc = 3.454

Length of Arc = 3.5 cm Approx.
