Question

A circle with a diameter of 10 cm and a central angle of 30° is shown. What is the length, to the nearest tenth, of the arc formed by the 30° angle?

Answer 1

9514 1404 393

Answer:

2.6 cm

Explanation:

The full circle is 360°, so an arc of 30° will have 30/360 = 1/12 of the measure of the circumference of the circle.

arc length = πd/12 = π(10/12) ≈ 2.6 cm
