Question

in fig find the area of shaded region use pie = 3.14​

Answer 1

Answer:

area of shaded region=area of bigger square-area of unshaded region

so find the area of unshaded region first

side of smaller square =diameter of semicircle

radius of semicircle =(14-6)/4=8/4=2cm

therefore, area of unshaded region=4×area of each semicircle+area of smaller square

=4×(3.14×2×2÷2)+16

=4×(6.28)+16

=25.12+16

=41.12sqcm

area of bigger circle=14×14=196sqcm

area of shaded region=196-41.12

=154.88sqcm
