Question

Calculate the arc length of GH in terms of pi.

Answer 1

10π/3 mm

Explanation:

Arc length is:

s = rθ × π/180

where r is the radius and θ is the angle in degrees.

Here, r = 10 mm and θ = 60°.

s = (10) (60) (π/180)

s = 10π/3

Another way to calculate it is to find the entire circumference then divide by 6, since 60° is one-sixth of 360°.
