Answer 2

Answer:

19 sq cm

Step-by-step explanation:

if a figure is inscribed in another same figure of different sizes they are said to be similar

so area of semi circle 1 is 3.14 *8 = 25.12

semi circle 2 is 3.14*2 ( if two shapes are similar then the corresponding ratios of sides be equal or 1 is to 2)

finally shaded region is equal to 25.12 -6.28= 19 sq cm
