Correct answer is (d) 10π cm^{2}

**Explanation**: The area of the circle is = πr^{2} = π5^{2} = 25 πcm^{2}

The area of the pentagon is 5 x (1/2 x s x h) = 5 x (1/2 x 4.33 x 2.5) = 5 x 5.4125 = 27.0625 cm^{2}

Therefore, the area of the shaded part of the circle is 25 π cm^{2} - 27.0625 cm^{2} = 10 π cm^{2}
