The shaded area = 2 * area of the segment in each circle
area of 1 segment = area of sector - area of triangle formed by the 2 radii
= 1/2 * 4^2 * pi/3 - 2*2 sqrt3
= 8 pi/3 - 4 sqrt3
so area of shaded part = 2 * the above
= 16pi/3 - 8 sqrt3
Answer: where is the picture so we can help you
Step-by-step explanation:
Answer: Your answer should be 1/2 which i think is B in this case
Decrease = New number - Original Number
% Decrease =
× 100
