Question

A circle has a radius of 3. An arc in this circle has a central angle of 20. What is the length of the arc?

Answer 1

Answer:

Step-by-step explanation:

1/3 pi

Answer 2

Circumference of whole circle =
$\pi \times 3 \times 2$
360÷20=18
$\frac{1}{18} \times 6\pi = \frac{1}{3} \pi$
hence length of arc = 1/3 pi
