Answer:

The length of the arc GH is approximately 3.14 meters (or π)

Step-by-step explanation:

The length of an arc whose measure equals the measure of the central angle Ф and the radius of the circle r is:

  • L = (Ф ÷ 360°) × 2π r

Let us solve the question using the rule above

∵ The measure of arc GH is 30°

∴ Ф = 30°

∵ The radius is 6 meters

∴ r = 6 meters

→ Substitute them in the rule above

∵ L = (30° ÷ 360°) × 2π × 6

∴ L = [tex]\frac{1}{12}[/tex] × 12π

∴ L = π

→ Use π ≈ 3.14

∴ L ≈ 3.14

∴ The length of the arc GH is approximately 3.14 meters (or π)
