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:
The answer is 8
Step-by-step explanation:
Because 4x12 is 48 and so is 6x8
10 / (2/5)...when dividing with fractions, flip what u r dividing by, then multiply
10 * 5/2 = 50/2 = 25...so there are 25 of them
7 that is what t should be
Step 2 would be B. Write down the facts and figures.
