Find the area of the enclosed region, PXROY correct to the nearest whole number
- A.
96cm^{2} - B.
116cm^{2} - C.
154cm^{2} - D.
192cm^{2} - E.
385cm^{2}
Correct Answer: Option A
Explanation
Area of the bigger semi circle P x RO =
πr^{2}2
=
227
x
492
= 77cm^{2}
2nd Area of the smaller circle DYO =
227
x
3.5^{2}2
= 19.25
Total Area = 77 + 19.25 = 96.25 = 96.00
