Q11 of 36 Page 253

Select a proper option (a), (b), (c) or (d) from given options and write in the box given on the right so that the statement becomes correct:

and are the two mutually perpendicular radii of a circle having radius 9 cm. The area of the minor sector corresponding to AOB is cm2( = 3.14)


Given radius (r)= 9 cm


∵ They are perpendicular to each other θ = 90o


area of the minor sector =


=


=


= 63.585 cm2


So, option(b) is the correct answer.
