Question

find the shaded area if diameter of the circle is 14cm, AC = BC​

Answer 1

Answer:

Step-by-step explanation:

AC = DE = 14cm (given)

⇒ AB = BC = 7 cm (given)

Area of the shaded region = Area of rectangle ACDE + Area of semicircle DEF – 2 × Area of quadrant

∴   Area of rectangle = Length × Breadth

Area of semicircle = 1/2π(r2)

2 × Area of quadrant  =  π/4(r2)

∴   Area of shaded region = 14 × 7 + π/2(7)2 – 2 × π/4 (7)2

= 98 + 49π/2 - 49π/2

= 98 cm
