5.3 minutes.
First, let's calculate the volume of the tank. That will be the area of the base multiplied by it's length. And since it's base is a circle, the area is pi*r^2. So:
V = l*pi*r^2
V = 3.5 * pi * (2.2/2)^2
V = 3.5 * pi * (1.1)^2
V = 3.5 * pi * 1.21
V = 4.235 * pi
V = 13.30464489
So the tank has a volume of about 13.3 ft^3. Now simply divide that volume
by the rate of incoming fluid. So
13.3 / 2.5 = 5.32
Rounding to 2 significant figures gives a time of 5.3 minutes.

263.76 cm is the minimum amount of paper she will need to wrap the entire container.
<u>Step-by-step explanation:</u>
As we know that the equation for surface area of a cylinder,
Surface area of cylinder = ![2\pi r^{2}+2 \pi r h](https://tex.z-dn.net/?f=2%5Cpi%20r%5E%7B2%7D%2B2%20%5Cpi%20r%20h)
Where,
r - the radius of the cylinder. Here given diameter (D) as 6. So,
![r=\frac{D}{2}=\frac{6}{2}=3 \mathrm{cm}](https://tex.z-dn.net/?f=r%3D%5Cfrac%7BD%7D%7B2%7D%3D%5Cfrac%7B6%7D%7B2%7D%3D3%20%5Cmathrm%7Bcm%7D)
h - the height of the cylinder (given as 11 cm). The value for pi = 3.14. Now, calculate the surface area of the cylinder as
![A=2(3.14)(3)^{2}+2(3.14)(3)(11)](https://tex.z-dn.net/?f=A%3D2%283.14%29%283%29%5E%7B2%7D%2B2%283.14%29%283%29%2811%29)
A = 56.52+ 207.24 = 263.76 cm
