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

the area of the shaded sector is equal to 1/2r^2θ. which of the following must be true about the value of θ?

The correct answer is second option.

θ = measure <BAC in radians.

Step-by-step explanation:

Formula:-

The area of sector with central angle θ and radius r

Area = 1/2 r²θ

Where θ is in radians.

It is given that,

The area of the shaded sector is equal to 1/2r²θTherefore the correct answer is option 2.

θ = measure <BAC in radians.
