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

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

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

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

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

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

Please help will mark brainlist

4vir4ik [10]

Answer:

I believe it is 8.0 units.

Step-by-step explanation:

I may be wrong, but bare with me:

X and Y have negative and positive meaning depending on the quadrant, so if it is correctly put, the answer would be 7.6 units. Rounded to the nearest tenth would be 8.0

Hope this helps!
