Firstly, find the radius with the formula diameter (d) : 2
8 : 2 = 4 cm
The Vilume formula is r²hπ = 4²*12*π = 16*12*π = 192π cm³
Your exercise says to use "3" as a value for π
Then V is 192*3 = 576 cm³
Answer: last option
Step-by-step explanation:
You need to remember the identity:

You need to find the cosine of angle P, then, you can identify in the figure that:

Therefore, the next step is substitute these values into
, then you get:

You can observe that this matches with the last option.


notice your "a" and "b" components, to get the distance "c" from the center to either foci and the vertices, of course, are h + a, k and h - a, k
