Answer:
Arc length of arc BC is 6.98 units or roughly 7 units.
Step-by-step explanation:
First recall that the formula for the circumference of a circle is C = 2πr, where r is the radius. Here the radius is 4 units. so the circumference of the (entire) circle is C = 2π(4 units) = 8π units.
The central angle for the arc shown in yellow is 100 degrees. The length of this arc is a fraction of C as found earlier:
100
------- * 8π units = 800π/360 units, or 6.98 units (about 7 units).
360
Arc length of arc BC is 6.98 units or roughly 7 units.
