Question

find the area of the shaded region
​

Answer 1

Answer:

diameter of circle =side of square see,

so area of square=21²=441

area of circle=π×(21/2)²

=346.185

area of shaded portion =area of square-area of circle

=441-346.185=94.815

Answer 2

Area of the square = side² = (21cm)² = 441cm²

Area of the circle = πr² = (22/7)*(21/2)*(21/2)cm² = 346.5cm²

hence, area of the shaded region = 441cm²-346.5cm² = 94.5cm².
