Four equal circles are described at the four corners of a square so that each touches two of the others. The shaded area enclosed between the circles is 24/7 m2. Find the radius of each circle.

ar of shaded region =24/7 
let the side of sqare be s 
ar of square =S2
ar of 4 quadrants =4* 1/4 *22/7 *r2
now r=S/2
24/7 =  S2(1-11/14)
24/7 =S2*3/14
S2 =24*14/7*3
S2 =16
therefore r=4/2  
 r = 2
