Answer 1

Answer:

Milk supplied in the morning=56L

Milk supplied in the evening=44L

Milk supplied in a day=100L

Cost of Milk=Rs. 30/L

So, cost of 100L Milk=30×100

=3000 Rs./day.

Answer 2

Answer:

Therefore the height of the cylinder is 8 cm.

Step-by-step explanation:

As per the data provided in the given question.

The given data is as follows,

The radius of a cylinder (r) is 1 cm and the volume of a cylinder(V) is$8\pi$.

We have to find the height of a cylinder (h).

Here we will be using the formula of the height of a cylinder.

$h=\frac{V}{\pi r^{2} }$

Now we will substitute the value of V and r in the above formula.

Further, We get

$h=\frac{8\pi }{\pi\times 1^{2} }$

Now we will cancel the $\pi$ from the above value.

We get,

$=\frac{8}{1}\\=8$

Therefore the height of the cylinder is 8 cm.
