Best ResponseYou've already chosen the best response.0well, so suppose those 2 quarters of a circle are from the whole circle of radius 10. Then The area of that circle would be pi*r^2= pi*10^2=100pi. Half of that would be 50pi, so the area of the white regions is 50pi.

Best ResponseYou've already chosen the best response.0I got that from the fact that two quarters of a circle make a semicircle. So now, subtract 50pi from the area of the rectangle which is: (10+10)*10=20*10=200
