The area bounded by the curve x=4-y² and the Y -axis is
Options
- A16 sq units
- B32 sq units
- C32 3 sq units
- D16 3 sq units
Correct answer
C. 32 3 sq units
Step-by-step solution
Given curve x=4-y² and Y -axis. The formed area is A B C O A aligned &=2 area of A B O A &=2 ₀⁴ 4-x d x &=2 [- (4-x)^ 3 / 2 3 / 2 ]₀⁴ &=2 [- 2 3 0+ 2 3 (4)^ 3 / 2 ] &= 4 3 8= 32 3 sq units aligned
