Find the area of the shaded part in the following figure. (π = 3.14)

Sum

Area of the shaded part = Area of semicircle – Area of the triangle

= `(1/2 pi"r"^2) - (1/2 "bh") "cm"^2`

= `1/2 xx 3.14 xx 7 xx 7 - 1/2 xx 14 xx 7 "cm"^2`

= `(153.86)/2 - 49 "cm"^2`

= 76.93 – 49 cm²

= 27.3 cm²

∴ Area of the shaded part = 27.93 cm² ...(approximately)
