1.	four equal circles are described about four corners of square so that each circle touches two of the others find area of space enclosed between of the the circumference of the circles each side of square measuring 24cm
Answer» Shaded area = area of square - sum ofareasof 4 quadrantsLet the radius of circle be r cmthen side of square will be 2r cmA/q24 =(2r)² - 4×(1/4)×πr² =4r² - 22/7 r²⇒24/ = 6r²/7⇒r² =28⇒r =√28cmhence , the radius of each circle is 5.29 cm
