Question

find the area of a shaded part of the given circle...where half part is shaded and radius given 7 m​

Answer 1

Answer:

Area of shaded portion=Area of sector-Area of Right angled triangle.

Area of sector=4π×(7cm)2=38.5cm2

Area of triangle: 21×(7cm)×(7cm)=24.5cm2

Thus Area of shaded portion=(38.5−24.5)cm2=14cm2

Answer 2

Step-by-step explanation:

Area of shaded portion=Area of sector -

Area of Right angled triangle.

$Area of sector= \frac{4π×(7cm) {}^{2} }{4} =38.5cm2$

$Area of triangle: \frac{1}{2} ×(7cm)×(7cm)=24.5cm {}^{2}$

Thus Area of shaded portion = (38.5 − 24.5)cm² = 14cm²
