Options
- A2 3 sq. units
- B4 3 sq. units
- C8 3 sq. units
- D16 3 sq. units
Correct answer
D. 16 3 sq. units
Step-by-step solution
aligned & Required area = _ -1 ^3 (1+y)- ( y^2-1 2 ) d y & = _ -1 ^3 ( 3 2 +y- y^2 2 ) d y & = [ 3 2 y+ y^2 2 - y^3 6 ]_ -1 ^3 & = ( 9 2 + 9 2 - 27 6 )- ( -3 2 + 1 2 + 1 6 )= 16 3 aligned
