For any circle, which ratio is equal to the number n? select all that apply. plsss

Options A-C-F

Step-by-step explanation:

we know that

The circumference of a circle is equal to

 or  

where

D is the diameter and r is the radius

therefore

 or

The number pi is the ratio circumference - diameter or is the ratio circumference - 2 times radius

The area of the circle is equal to

therefore

The number pi is the ratio Area - radius squared

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
