Use the method of cylindrical shells to find the volume generated by rotating the region bounded by the given curves about the s

Furkat [3]

Answer:

$\frac{16\pi}{3}$ .

Step-by-step explanation:

I graphed the region in the image below. The blue line is y=3, the purple line is x=1 and the green curve is y = $4x-x^{2}$ . The shaded region in blue is the region we are going to rotate.

Now, to find the volume v= $2\pi \int\limits^a_b {p(x)h(x)} \, dx$ where a=1, b=3 (left and right points of the region), p(x) is the distance from the rotation axis to the diferential Δx, we say p(x)=x and h(x) is the height of the region, in this case is h(x)= $4x-x^{2}-3$ . Then,

v = $2\pi \int\limits^1_3 {x(4x-x^{2}-3)} \, dx$

= $2\pi \int\limits^1_3 {4x^{2}-x^{3}-3x} \, dx$

= $2\pi (\frac{4x^{3}}{3}-\frac{x^{4}}{4}-\frac{3x^{2}}{2})^{3}_1$

= $2\pi (36-\frac{81}{4}-\frac{27}{2}-\frac{4}{3}+\frac{1}{4}+\frac{3}{2})$

= $2\pi*\frac{8}{3}$

= $\frac{16\pi}{3}$ .

Step-by-step explanation:

They are looking for the y intercept. I am assuming that the scale on the x and y axis are counting by 1's. If you start at the origin (0,0) and count up, you will see that the dotting line is going through (0,5)
