. The area of the shaded region, shown in the diagram below, is:

Best Answer

Answer ||| C

Solution ||| Clearly Diameter of the circle = Diagonal BD of rectangle ABCD

∴ Diameter = 

Let r be the radius of the circle . Then , r = (10/2) cm = 5 cm

Area of rectangle ABCD = AB × BC = (8 × 6) cm² = 48cm²

Area of the circle = πr² = 3.14 × (5)² cm² = 78.50cm²

Hence,

Area of the shaded region = Area of the circle – Area of rectangle ABCD

= (78.50 - 48) cm² = 30.50 cm²
