KCET2024MathematicsArea Under Curves
The area of the region bounded by the line y=3 x and the curve y=x^2 sq units is
Options
- A10
- B9 / 2
- C9
- D5
Correct answer
B. 9 / 2
Step-by-step solution
We have, y=3 x and y=x^2 3 x=x^2x=3 and x=0 are the points of intersection. Now, area = ₀^3 (3 x-x^2 ) d x= . 3 x^2 2 |₀ ^3- . x^3 3 |₀ ^3=3 9 2 - 27 3 = 27 2 -9= 9 2 sq units
