Answer:
$16.50
Step-by-step explanation:
Consider a circle with radius
centered at some point
on the
-axis. This circle has equation

Revolve the region bounded by this circle across the
-axis to get a torus. Using the shell method, the volume of the resulting torus is

where
.
So the volume is

Substitute

and the integral becomes

Notice that
is an odd function, so the integral over
is 0. This leaves us with

Write

so the volume is

Answer:
4,-4 I think
Step-by-step explanation:
My brain is off right now so might be wrong
slope intercept form is y=4/3x-2 slope is 4/3 and y=-2
