In the given figure, a circle with centre B overlaps another circle with centre A and a square. The ratio of areas of P and Q is 5 :4 and the area of Q is\[\frac{1}{8}\]the area of circle B. The radii of circle A and circle B are 10 cm and 8 cm respectively. Find the area of the unshaded part of the figure. (Take\[\pi =\text{3}.\text{14}\].)

A)  \[\text{449}.\text{75 c}{{\text{m}}^{\text{2}}}\]    

B)         \[\text{52}0.\text{6}0\text{ c}{{\text{m}}^{\text{2}}}\]

C)  \[\text{563}.\text{72 c}{{\text{m}}^{\text{2}}}\]    

D)         \[\text{45}0.\text{92 c}{{\text{m}}^{\text{2}}}\]
