WebFrom Fig. A area of the shaded region is A A ( 4 − π) Similarly with Fig B the area is A B = ( 4 − π) Now when you subtract it from the whole you get the four shaded areas in the given question. The shaded area is A = 4 − ( 4 − π) − ( 4 − π) = 2 π − 4 Share Cite Follow edited Oct 29, 2014 at 14:35 Null 1,292 3 17 21 answered Oct 29, 2014 at 14:16 django rest api 만들기
