Question

Given a central angle of 100 in a circle with a radius of 7 in., what is the intercepted arc length of the central angle?

**Use 3.14 for π and round to ONE decimal place.

Answer 1

12.2 inches

Explanation:

Write and solve a proportion.

Arc length / circumference = central angle / 360°

x / (2π × 7) = 100° / 360°

x = 12.2

The arc length is 12.2 inches
