COMEDK2020MathematicsArea Under Curves
The area bounded by the curve x=4-y² and the Y -axis is
Options
- A32 sq units
- B16 sq units
- C16 3 sq units
- D32 3 sq units
Correct answer
D. 32 3 sq units
Step-by-step solution
We have, x=4-y² y²=-(x-4) aligned Required area &=2 ₀⁴ y d x=2 ₀⁴ 4-x d x &=2 [ -(4-x)^ 3 / 2 3 / 2 ]₀⁴ &= -4 3 [(4-4)^ 3 / 2 -(4-0)^ 3 / 2 ] &= -4 3 (-8)= 32 3 sq units aligned
