In order to solve for this, we need to find the volumes of both the cylinder and cone described.
In order to find the area of the cylinder:
We use the equation V=
So, V=
The volume of the cylinder is therefore approximately <span>1809.56
For the cone:
V=
So, V=
Thus, the volume of the cone is 113.1
We add these volumes together to derive the solution, which is 1922.66

Answer:
Choice B
Step-by-step explanation:
The first step is to write the polar equation of the conic section in standard form by dividing the numerator and denominator by 6;
The eccentricity of this conic section is thus 2/3, the coefficient of cos theta. Clearly, the eccentricity is between o and 1 implying that this conic section represents an Ellipse.
Lastly, the ellipse will open towards the left since we have positive cos theta in the denominator. The only graph that meets the conditions is graph B.
