Question

Help me ?

The equation of a circle is shown below.

(x -5)2 + (y + 2)2 = 64

The radius of the circle is _______ units.

Answer 1

compare it wid standard circle equation :

\((x-h)^2 + (y-k)^2 = \color{red}{r}^2\)

Answer 2

\(\color{red}{r}\) is the radius

Answer 3

i dont get how i solve this.

Answer 4

given equation :-

\((x -5)^2 + (y + 2)^2 = 64 \)

\((x -5)^2 + (y + 2)^2 = \color{red}{8}^2\)

Answer 5

comparing wid the standard equation, r = 8, so radius = 8

Answer 6

Okay i kind of get it but its still confusing .

Answer 7

its okay, do 2-3 more problems like these and you will feel comfortable im sure :)

Answer 8

Thank you :)

Answer 9
