Use the method of cylindrical shells to find the volume v generated by rotating the region bounded by the given curves about the
lys-0071 [83]

The volume of the solid of revolution is \frac{7\pi}{3} cubic units.

<h3>How to find the volume of a solid of revolution with respect to an axis parallel to a Cartesian axis</h3>

The statement has been represented in the image attached below, the formula for the solid of revolution is presented below:

V = \pi \int\limits^{1}_{0} {[5\cdot y^{2}-2]^{2}} \, dy (1)

V = \pi \int\limits^{1}_{0} {(25\cdot y^{4}-20\cdot y +4)} \, dy

V = 25\pi\int\limits^1_0 {y^{4}} \, dy -20\pi\int\limits^1_0 {y^{2}} \, dy +4\pi\int\limits^1_0\, dy

V = \frac{7\pi}{3}

The volume of the solid of revolution is \frac{7\pi}{3} cubic units. \blacksquare

For a 180° rotation about the origin, write the coordinates of each point in the table.
Marta_Voda [28]

Answer:

Hey, you don't include any points, but I can give you the rule for an 180 degree rotation.

You just need to write the same points, but negative. So going from (x,y) to

(-x,-y).

As an example let's say you wanted to rotate (3,-4) 180 degrees about the origin. The the point after the rotation would be (-3,4).

Hope that helps!
