Let's try to complete the squares.
The x-part starts with , which is the beginning of . So, we'll think of as
Similarly, we have that
So, the equation becomes
Now we have writte the equation of the circle in the form
When the equation is in this form, everything is more simple: the center is and the radius is .
Answer:
P
v = 794.0275 in³
Q
v = 1,307.81 in³
Step-by-step explanation:
volume of cone
v = πr²h
----------------------------
cylinder P
v = 3.14 * (4.25²) * 14
v = 794.0275 in³
-----------------------------
cylinder Q
v = 3.14 * (7²) * 8.5
v = 1,307.81 in³
