X^2+(y-2)^2=4 is a circle centered at (0,2) with radius 2.
Thus, when you rotate it around the y-axis (around x=0),
you get a sphere with radius 2.
((which is centered at (x,y,z)=(0,2,0), if you take y to be
the vertical axis ... not that you need to know this for volume))

Volume of a sphere formula: V = (4/3)πr^3.
<span>1. B. 2.5x
2. A. 1/2 y- 4
3. D. v=15.00n </span>
Answer:
Step-by-step explanation:
The exterior angle in a triangle is equal to the sum of the interior opposite angles in a triangle
Therefore,
Now solve for x
Now let's solve for the exterior angle
