In Cartesian coordinates, the region (call it
) is the set

In the plane
, we have

which is a circle with radius
. Then we can better describe the solid by

so that the volume is

While doable, it's easier to compute the volume in cylindrical coordinates.

Then we can describe
in cylindrical coordinates by

so that the volume is

Answer:
The answer is 11.
Step-by-step explanation:
We will use PEMDAS in this situation.
7 + 2 = x - 4 / 2
7 + 2 = x - 2 [divide first
9 = x - 2 [add the 7 and 2]
+2 +2 [the 2 cancels out]
11 = x
Your answer is 11.
I hope this helped!

Each pencil cost $2.
Explanation: She had $24 before buying the pencils and after she had $10. 24-10=14 so the total she spent on pencils was $14. She bought 7 pencils so you divide 14 by 7 (14/7=2) which equals 2. So each pencil cost $2.
