Question

PLEASE PLEASE HELP ME WILL FAN AND MEDAL!!!!

Answer 1

A circle is represented by the equation shown below.

(x - 7)2 + (y - 8)2 = 121

Which statement is true?

The circle is centered at (7, 8) and has a diameter of 11.

The circle is centered at (7, 8) and has a radius of 11.

The circle is centered at (-7, -8) and has a radius of 11.

The circle is centered at (-7, -8) and has a diameter of 11.

Answer 2

tricky because of that "radius, diameter" business

Answer 3

\[(x - 7)^2 + (y - 8)^2 = 121 \] looks like \[(x - h)^2 + (y - k)^2 = r^2 \] a circle with center \((h,k)\) and RADIUS \(r\)

Answer 4

that makes the radius \(\sqrt{121}=11\) not the diameter

Answer 5

oops still not A
go with B

Answer 6

bahaha okay thank you so much :)
