The centroid of shaded area can be obtained

By taking quarter circle of radius 20 & subtracting Semicircle of radius 10 form it.

Now, $X = (\sum A_i x_i)/( \sum A)= 1096.42/157.08 = 6.98 cm \\ Y = (\sum A_i y_i)/( \sum A)= 2001.2/157.08 = 12.74 cm$

Centroid of shaded region is $(6.98, 12.74)$ cm
