In the circle shown below, ∠bac is a central angle, r is the length of ab, and θ is the measure of ∠bac in degrees.

which of the following would be used to derive the formula for the area of sector bac?

see attached picture and choices

Option 4 is the right answer.

Step-by-step explanation:

As we know in the given circle area of minor segment having an angle ∅ and radius of the circle r is shown by

Area of the minor segment / Area of the circle = ∅ / 360° (∅ is in degrees)

Area of the minor segment / πr² = ∅ / 360°

Area of the minor segment = (∅ / 360°) × πr²

Therefore Option 4 is the right answer.
