Rectangular diagonals intersection point coincides with the center of the circle. The length of the rectangle is equal to 8 and the width is equal to 2√2. The length of the circle radius is 2. Calculate the rectangle and the area of the common part (area of circle inside rectangle) of the circle.
Oh my God just finish it. Solution: r=2 a=8 b=2√2 h=2-((2√2)/2)=2-2√2 α(rad)=90°π/180°=π/2 A(area of segment)=(2^2(π/2-sin(90°)))/2=4(π/2-sin(90°))/2=2(π/2-1)=π-2 A Δ=A1+A2 A Δ=(π-2)+(π-2)=2π-4 A(area of the common part)=4π-2π-4=2π-4 Answer: A(area of the common part)=2π-4
