Question

Please Help!! Find the Polynomial!!

Answer 1

pi x² - 8pi x + 16pi

Explanation:

pi × (4 - x)²

pi × (16 - 8x + x²)

pi x² - 8pi x + 16pi

Answer 2

`\pi x^2-8\pi x+16\pi`

Explanation:

To find the area of the inner circle, we need to find its radius. Here, we can write the radius as 4 - x. Now, we can use the formula
`A=\pi r^2`:

A =
`\pi` *
`(4-x)^2`

We can expand the square:

A =
`\pi *(16-8x+x^2)=\pi x^2-8\pi x+16\pi`

Thus, the polynomial is
`\pi x^2-8\pi x+16\pi`.

Hope this helps!
