52. Find the area of shaded portion in the​

Answer 1

Answer:

area of quadrant of a circle= π r²

=π*10²

=314.15

area of square = a²

= 10*10

=100

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

= 314.15-100

=214.15

Answer 2

Answer:

square of side 10 CM

1. diagonal of square=radius of circle

diagonal= 10√2 CM= radius of circle

now area of shaded region = (area of quadrant)-(area of square )

area of shaded region= 1/4π(10√2) ^2 -10^2

=50(π-2) cm^2
