What is the length of the arc shown in red?

professor190 [17]

Answer:

≈ 18.8 cm

Step-by-step explanation:

The arc length is calculated as

arc = circumference of circle × fraction of circle

The central angle is equal to the arc subtending it, that is 60°

arc = 2πr × $\frac{60}{360}$

= 2π × 18 × $\frac{1}{6}$

= 36π × $\frac{1}{6}$

= 6π ≈ 18.8 cm ( to 1 dec. place )
