Evaluate Z Z Z
E
(x
2 + y
2
)dV
Where E lies between the spheres x
2 +y
2 +z
2 = 4 and x
2 +y
2 +z
2 = 9. (Hint:
Use spherical polar coordinates)

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
