ABCD is a square of unit length. Four circles unit radius are described with centres at A, B, C, D. The area common to the four circles is

In Fig 13,ABCD is a square of side 5.6 cm.As shown in the figure,four circles are drawn with centres A,B,C and D respectively.Find the area of the shaded region in the diagram. (pi=22/7)

A square ABCD is inscribed in a circle of unit radius. Semicircles are described on each side as a diameter. The area of the region bounded by the four semicircles and the circle is (1) 1 sq. unit (2) 2 sq. unit (3) 1.5 sq. unit(4) 2.5 sq. unit

A wire of length 2 units is cut into two parts which are bent respectively to from a square ofside c units and a circle of radius r units if the sum of the sum of the areas of the square and the circle so fromed is minimum then

A wire of length 2 units is cut into two parts which are bent respectively to from a square ofside c units and a circle of radius r units if the sum of the sum of the areas of the square and the circle so fromed is minimum then

ABCD is a square inscribed in a circle of radius r. Then the total area (in square units) of the portions of the circle lying outside the square is

Four equal circle are described about the four corners of a square

ABCD is a square with side length 10. A circle is drawn through A and D so that it is tangent to BC. What is the radius of circle?
