Question

Answer the question above with the choices below.

A) Center: (8,10); Radius: r = 9
B) Center: (-7,8); Radius: r = 3
C) Center: (8,10); Radius: r = 3
D) Center: (-8,-9); Radius: r = 3

Answer 1

`{(x - 8)}^(2) + {(y - 10)}^(2) = 81`

`{(x + 7)}^(2) + {(y - 8)}^(2) = 9`

`{(x - 8)}^(2) + {(y - 10)}^(2) = 9`

`{(x + 8)}^(2) + {(y + 9)}^(2) = 9`

Explanation:

use circle equation and plug in the centers and radis.

Answer 2

the answer is C) Center: (8,10); Radius=3
