Answer:

A

Explanation:

So first you need to know the formula for the area of a segment of a circle which is... A = 0.5 × (θ - sinθ) × r²

*make sure that you do this question in RADIANS

You know that θ (the angle) is 90° which is equal to π/2 and the radius is 3, so from here you just plug in numbers to the equation.

A = 0.5 × ( π/2 - sin(π/2)) × 3²

A = 2.5685... sq units = 3 sq units
