Answer:
A
Step-by-step 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
