Question

In figure ,ABCD is a square of side 28 cm . with centers A,B,Cand D each circle touche extrenally two of the remaining three circles. find the area of the shaded region​

Answer 1

Now the radius of will be 28/2 = 14 cm

now according to the question the square will lodge 4 quaters of a circle which becomes a complete circle

as 4 x πr^2 /4 = πr^2 = 22x 14x14 / 7 = 616 sqcm

and area of square = 28 x28 = 784 sqcm

so area remained shared inside the square is 784- 616

= 168 sqcm
