Question

Find the area of shaded region in the given figure, where a circle is enclosed by a square ABCD of side 20cm.

• A. 100cm²
• B. 54cm²
• C. 86cm²
• D. 78.4cm²

Answer 1

The correct option is C

86cm²

Area of the square ABCD = ${20}^2$$c{m}^2$ = 400$c{m}^2$
Diameter of the the circle =20cm; radius =10cm
Area of circle = 3.14 X ${10}^2$ = 314 $c{m}^2$
Area of shaded region = Area of square- Area of circle =400$c{m}^2$ - 314$c{m}^2$ = 86$c{m}^2$
