area of white region = area of white region without considering grey region - area of grey region
= (22/7 * 2^2) - (22/7 * 1^2) = 22/7*(4 - 1) = 66/7 = 9.4285
since while area + inner circle together constitute 4*pi and the inner circle is pi therefore white area alone is 3*pi ans
A quarter-circle with radius R is drawn. Inside it, two semicircles and a circle are drawn as shown in the below figure. If the area of the white colored region is (Pi*R^2)/X then find the value of X?
A semicircle is inscribed in a right triangle as shown. What is the area of the shaded region in the figure?
