Question

A circle is represented by the equation below:

(x − 9)2 + (y + 8)2 = 16

Which statement is true?

The circle is centered at (−9, 8) and has a radius of 8.
The circle is centered at (9, −8) and has a diameter of 8.
The circle is centered at (9, −8) and has a radius of 8.
The circle is centered at (−9, 8) and has a diameter of 8.

Answer 1

my answer is C

Answer 2

is my answer correct?

Answer 3

nope

if r^2 = 16, what is r?

Answer 4

4?

Answer 5

good

so your radius is 4, not 8

check the answer choices again

Answer 6

If radius is 4, the diameter is 8

Answer 7

so it would be B

Answer 8

good job!
