Calculate the area enclosed by the curves x 2 = 2 - y , x 2 = y
Options
- A2 3 square units
- B4 3 square units
- C8 3 square units
- D11 3 square units
Correct answer
C. 8 3 square units
Step-by-step solution
x 2 = 2 - y ,   x 2 = y Intersection point ⇒ 2 - y = y ⇒ y = 1 ⇒ x = ± 1 A = ∫ - 1 1 [ ( 2 - x 2 ) - ( x 2 ) ] d x = 2 ∫ 0 1 ( 2 - 2 x 2 ) d x = 4 x - x 3 3 0 1 = 8 3 square units.
