A company packages its milk powder in cylindrical

Roman55 [17]

Answer:

704 cm²

Step-by-step explanation:

The circumference of the cylindrical container is given by 2πr.

Now, r = radius of the base

If the diameter of the base is 14 cm then the radius will be 7 cm.

So, the circumference = $\frac{2 \times 22 \times 7}{7} =44$ cm.

Now, the label around the surface of the container placed 2 cm from top and bottom.

Therefore, the width of the label is (20 - 2 - 2) = 16 cm and the length is 44 cm.

Hence, the area of each label is (44 × 16) = 704 cm² (Answer)

The sum of two numbers is 37. Their difference is 11. What is the smaller number?

raketka [301]

Hello from MrBillDoesMath!

Answer:

Discussion:

Let the numbers in the Question be call m and n. Then

m + n = 37

m - n = 11

Adding these 2 equations gives:

(m+ n) + (m - n) = 37 +11 =>

(m+m) + (n-n) = 48 =>

2m + 0 = 48 =>

m = 24.

As m + n = 37, 24 +n = 37 , so n = 13.

Thank you,

In the figure below, lines m and n are parallel. Line s is perpendicular to line m.

Rus_ich [418]

I think it would be 55 only because line P is 145 degrees so because line S is straight it is 90 degrees. So you would subtract the two (145-90) and would come up to B or 55.
