CD = CO = 7cm
But CO = 1/2 OB
=> OB = 14 cm

Area of shaded region = Area of quadrant AQBO - Area of semicircle ODBO
                                      => (1/4 pi (14)^2 ) - ( 1/2 pi (7^2))
                                     => 1/2 ( 0.5 * 196  \pi - 49  \pi )
                                   => 1/2 ( 98 pi - 49 pi)
                                    => 1/2( 49 pi)
                                       => 77 cm^{2}

Anonymous: 77cm^2 that is
