Acircular window is surrounded by a circular frame. the radius of the window is m - 2 and the radius of the full circle formed by the frame is m + 2. write a polynomial that represents the area of just the frame itself, not including the space covered by the window. (the area of a circle is given by a=pi r ^2, where "r" represents the radius of the circle.)

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

God with you!!!

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
