Answer 2

Answer:

Area of shaded region = area of large semi circle - area of small semi circular region

Step-by-step explanation:

Now area of semi circle is πr2/2

which is π = 22/7 r = 21/2 = 10.5 put the value

Now area of semi circular region of diameter 3.5

r = 3.5/2=1.75.

there are two diameter so 2 (1.75)

now 2(πr2/2) put the value

now take the diameter of large semi circle

Add the smaller two and larger one and subtract it with the whole semicircle and get the answer
