Answer 1

44cm²

Step-by-step explanation:

It doesn't matter in which part the circle is located. So area under the arc AQ +area under the arc QB=

area under arc AO+area under arc OB

Now AO=28cm(.:given)

and AQ is the radius of semicircle because

AO=(1/2) AB

And AQ=(1/4)AB

or AQ=(1/2)AO

so the area of the shaded region is

(pi×7)+(pi×7)

2×22/7×7

7 gets cancelled and leave the answer

2×22=44cm²
