Answer:
3.14
Explanation:
since you can see that the angle that is taken out of 90 degrees, and since 90 degrees in a quarter of a circle, you then know you need to find 3/4 of the original circle.
Since you know the radius is 2, you put that into the formula for a circle's area, pi x radius^2, and you do 3.14x2^2, which is 12.56.
Then, since you want to find 3/4 of the circle, you do 12.56/4, which is 3.14.
Hope this helped :)
