Options
- A[4 3 + 8 3 ] sq. units
- B1 2 [4 3 + 8 3 ] sq. units
- C[4 3 - 8 3 ] sq. units
- D1 2 [4 3 - 8 3 ] sq. units
Correct answer
A. [4 3 + 8 3 ] sq. units
Step-by-step solution
Given equation of circle is x²+y²=16 y²=16-x² y= 16-x² Required area is shaded. A=2 ~A ( OABCO ) aligned Area &=2 ₀² 16-x² dx &=2 [ x 2 16-x² + 16 2 ⁻¹ x 4 ]₀² &=2 2 2 12 +8 ⁻¹ 1 2 -0 =2 [2 3 +8 ( 6 ) ]=4 3 + 8 3 aligned
