victus00 [196]

Answer:

Mr Nelson will sell 115 more bottles of water than popcorn. First, you find the rate of popcorn and water being sold. That will be 147 bags divided by 3 and 216 bottles divided by 3. You get 49 bags and 72 bottles. You subtract those two numbers, 72-49=23. 23 is the number more waters sold than the popcorn. Finally, you multiply 23 by 5 days and you get 115. So it's 115 more waters sold than popcorn.

A circular window is surrounded by a circular frame. The radius of the window is m - 2 and the radius of the full circle formed
Vesnalui [34]

Answer:

Correct answer is:  A = 8 m π

Step-by-step explanation:

In fact, it is necessary to calculate the surface of the circular ring representing the circular window frame:

It's formula:

A = (R² - r²) π    where R = m + 2   and r = m - 2

A = ((m + 2)² - (m - 2)²) π = (m + 2 + m - 2) (m + 2 - m +2) π = 2m · 4 π

A = 8 m π
