Answer 1

Answer:

Step-by-step explanation:

join OC

You get three sector

Apply area of segment

i.e,area of sector - area of triangle

As all sectors have theta 90 (3 sectors)

So, theta/360*3.14*2root2*2root2

Since, diameter is 4 root2

Therefore radii is 2root 2

=270/360*3.14*2root2*2root2

Since 2root2*2root2=8

=3*3.14*2

=6.28*3

=18.84 cm^2

And area of triangle =ar(big triangle)

+ar(small )

=1/2*4*4+1/2*2root2*2root2

=8+4

=12 cm^2

Therefore,

Area of sectors - area of triangles

=shaded region

=18.84-12

Gives,

6.84cm^2

Therefore area of shaded region is 6.84 cm^2.
