Answer:
M = 5742π
Step-by-step explanation:
Given:-
- Find the mass of a solid with the density ( ρ ):
ρ ( r, θ , z ) = 1 + z / 81
- The solid is bounded by the planes:
0 ≤ z ≤ 81 - r^2
0 ≤ r ≤ 9
Find:-
Find the mass of the solid paraboloid
Solution:-
- The mass (M) of any solid body is given by the following triple integral formulation:
- We can write the above expression in cylindrical coordinates:
- Perform integration:
- The mass evaluated is M = 5742π
Answer:
56.36363636363636
Step-by-step explanation:
Percent change = 24 - 55
|55|
x 100 = -31
55
x 100 = -56.36363636363636 % (decrease)
Where: 55 is the old value and 24 is the new value. In this case we have a negative change (decrease) of -56.36363636363636 percent because the new value is smaller than the old value.
