Acircular helicopter landing pad has a radius of 200 feet. inside the circular pad, red paint covers the outer area evenly, with a width of x feet. white paint covers the inner area
write a polynomial that represents the area of the circle that is painted white. write your answers in terms of pie

Step-by-step explanation:

Radius of the circular pad = 200 feet

The red paint covers the outer area with a width of x feet and white paint covers the inner area. Since, the width of the area covered by red paint is x feet, the radius of the smaller circle covered with white paint will be 200 - x feet, as shown in the image below.

So,

We have the radius of the circle covered with white paint equal to = r = 200 - x

Area of a circle is calculated as:

Using the value of r, we get:

This polynomial represents the area of the circle that is painted in white.

the solution is 12x-6y

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
