Question

Find the volume of solid by revolving the region bounded by the x-axis and the graph y=x^3+x^2+1 where x=1,x=3 about the y -axis?​

Answer 1

Answer:

2a=b+c

\begin{gathered}2a = (2)^{2} + (2) \\ 2a =4 + 4 \\ 2a = 8 \\ a = 8 \div 2 \\ a =4 \end{gathered}

2a=(2)

2

+(2)

2a=4+4

2a=8

a=8÷2

a=4

Step-by-step explanation:

In quadratic

prove that sabte

2a=b+c.
