Fig Figure

Fig Figure
write a definite integral that represent the volume of the solid in fig 1?

0 volume=?
figure 1 is here http://scidiv.bcc.ctc.edu/dh/math152/M125Sp04Q3A.pdf

In figure 1, the line is x^2+1
I think the figure is kinda poorly drawn…but anyway, the distance between f(x) and y=0 will give you heigth, and since it is a square, it gives you your length.
We are finding the infite some of square sections to produce a volume.
Integrate (x^2+1)^2 from a to b.
