Answer 1

Step-by-step explanation:

1. Area of shaded region = area of square - area of circle.

=(20×20)-( 3.14×10×10)

= 400-314

=86 cm²

2. diameter = (6×6+8×8)^½ =100^½ =10 cm.

radius =5 cm

therefore,

area of shaded region = area of circle - area of rectangle.

=(3.14×5× 5) - (6×8)

=78.5-48

=30.5 cm²
