​

Answer 1

Answer:

the area of shaded region =area of square- area of circle

20×20-3.14×100

=86cmsquare

Answer 2

Answer:

Since the circle is drawn in a square,

the diameter gives the side of the square,

Given,

. Radius = 10 cm

diameter = 20cm

area of square = side × side

400cm^2

area of circle = pie R^2

3.14×100

= 314cm^2

Area of shaded portion = 400cm^2 - 314cm^2 = 86cm^2.

therefore ans. is 84cm^2
