Answer:
please mark brainliest..please
find radiuses by dividing by 2 : 21/2 , 14/2, and 7/2
firstly you have to find the area of the big circle = pi r^2= 22/7 × 21/2=33cm^2
then you have to add the areas of the small 2 circles= 22/7(7+7/2)=33cm^2
ohh there is a mistake in the question because this is not possible
otherwise the shaded region will be 0 so check the question again.
sorry
