Find the area of the shaded section round your answer to the nearest whole number you must multiply by pi
A. 3 sq units
B. 2 sq units
C. 2.6 sq units
D. 7 sq units

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

0.02040816326

168

step-by-step explanation:

i am pretty sure that the answer is 168
