The area bounded by the curve y= ( x 3 ) , x -axis and lines x=0 and x=3 is
Options
- A9
- B0
- C6
- D3
Correct answer
C. 6
Step-by-step solution
Required area = _ x=0 ^ x=3 y d x= ₀^ 3 ( x 3 ) d x Let x 3 =t d x=3 d t Also, when x=0t=0x=3 = Then, When t= Then, required area = ₀^ t(3 d t)=3[- t]₀^ =-3[ - 0]=-3(-1-1)=-3(-2)=6
