Question

For a circle of raduis 6feet, find the arc length of a central angle of 6

Answer 1

Length of a circumference=2πr
r=radius=6 feet.
lengt of this circumference=2π6 feet=12π feet.

1 circumference=360º; then:

360º-------------------12π feet
6º----------------------    x

360º * x=6º * 12π feet
x=(6º * 12π feet) / 360º=π/30  feet (≈0,105 feet).

Solution: π/30 feet
