Pls refer to the attachment. for the namings .

r = 28/2 = 14cm

Area of shaded region = Area of quadrant OBC - Area of ∆OBC

Area of shaded region = $\frac {πr^2}{4}$ - $\frac {r^2}{2}$

Area of shaded region = $\frac {22 * 14^2}{7 * 4}$ - $\frac {14^2}{2}$

Area of shaded region = $\frac {22 * 196}{28}$ - $\frac {196}{2}$

Area of shaded region = 22*7 - 98

Area of shaded region = 154 - 98

Area of shaded region = 56cm^2
