Answer:

part 1: A

part 2: A

Step-by-step explanation:

Part 1:

I think it is A (c ≤ 56), since it should be less than or equal to, due to it describing how many are left : 56 and less are left

B can't be right even though it is less than or equal to, since it says that -56 cans are left to collect: nonsense

Part 2:

A represents c ≤ 56

C represents c ≤ –56

B represents c ≥ 56

D represents c ≥ –56

thus, answer is A

A special liquid is held in a tank described as (x 2 + y 2 ) ≤ z ≤ 1 in a Cartesian coordinate system. Assume that the density o

vivado [14]

Since $\rho=\dfrac mV$ (density = mass/volume), we can get the mass/weight of the liquid by integrating the density $\rho(x,y,z)$ over the interior of the tank. This is done with the integral

$\displaystyle\int_{-1}^1\int_{-\sqrt{1-x^2}}^{\sqrt{1-x^2}}\int_{x^2+y^2}^1(2-z^2)\,\mathrm dz\,\mathrm dy\,\mathrm dx$

which is more readily computed in cylindrical coordinates as

$\displaystyle\int_0^{2\pi}\int_0^1\int_{r^2}^1(2-z^2)r\,\mathrm dz\,\mathrm dr\,\mathrm d\theta=\boxed{\frac{3\pi}4}$
