Question

What is the length of an arc defined by a 60 degree central angle in a circle with a radius of 5 in.?

Answer 1

Answer:

5.24 in

Step-by-step explanation:

The arc length is calculated as

arc = circumference × fraction of circle

     = 2πr × $\frac{60}{360}$

     = 2π × 5 × $\frac{1}{6}$

     = $\frac{10\pi }{6}$ ≈ 5.24 in (2 dec. places )
