The area of the region bounded by the curve ( y=x² ) and the line ( y=16 ) is
Options
- A( 32 3 ) sq. units
- B( 256 3 ) sq. units
- C( 64 3 ) sq. units
- D( 128 3 ) sq. units
Correct answer
B. ( 256 3 ) sq. units
Step-by-step solution
Given curve, y=x² (1) and given line, y=16 (2) Therefore, required area is given by 2 Area of region OAC array l =2 ₀¹⁶ y d y =2 2 3 [y^ 3 2 ]₀¹⁶=2 2 3 (16)^ 3 2 =2 2 3 (4)³= 256 3 array
