Question 74860
(c) is correct


Area of the circle = {{{pi*r^2 = 3.14*3^2 = 3.14*9 = 31.4 - 3.14 = 28.26}}} sq. units.


The side of the square is {{{a = 2r = 6}}}. 
Area of the square = {{{a^2 = 6^2 = 36}}} sq. units


Reqd. area = (Area of the square) - (Area of the circle) = 36 - 28.26 = 7.74 sq. units.
