Answer 2

Answer:

the circle have the same radius let that be x

Step-by-step explanation:

so side of the square is equal to diameter of the circle that is 2x

so area of square is 4x^2

area of one circle is pie×x^2

the part included is sector

so it's area will be pie×x^2/4

the are of 4 such will be 4× pie×x^2/4

=pie×x^2

area to find is 4x^2-piex^2 (pie=22/7)

(4-pie)x^2

6/7x^2
