Find the area of the shaded region of the given figure, where ABCD is a square side 7 cm and sectors of radius 2.1 cm each are drawn at its four vertices. Use π = 22 7 Share with your friends Share 2 Vijay Kumar Gupta answered this Dear Student, From the given figure, the area of shaded portion is given by, Area of four circles each with radius 2.1 cm-area of four sectors each with radius 2.1 cmIt can be seen that the center of each circle lie at the vertex of square. So each of the sector is a quadrant of a circle.Therefore, the four sectors forms the four quadrant of a circle. So the combined area of four sectors is area of a single circle with radius 2.1 cm.Thus, the required area of shaded portion is, =4×πr2-1×πr2 =4πr2-πr2 =3πr2 =3×227×2.1×2.1 =3×22×0.3×2.1 =41.58 cm2 Regards 0 View Full Answer Anny Pandya answered this Area of shadedegion =area of 4 circle- area of 4 sector -1
