Answer 3

the eqn is:
(x-h)^2+(y-k)^2=r^2

Answer 4

r is your radius

Answer 5

just take the square root of 64, that means the radius is 8.

In general, a circle is written as:

(x - A)^2 + (y - B)^2 = r^2

where (A,B) is the center point and r is the radius.

Answer 6

sorry you were already there... my bad Chelsea04 :)

Answer 7

h, k is more standard, but it's late for me, so I'm just making up letters since it doesn't really matter. :)

Answer 8

good luck! later

Answer 9

so do you do 64 / 8?

Answer 10

the equation says r^2
but r is your radius
so what you need to do is to sqrt 68

Answer 11

*64

Answer 12

Oh! I got 8 (: @Chelsea04

Answer 13

yea, that's your radius :)

Answer 14

just remember that the equation gives r^2 not r

Answer 15

okayy! Last questin!

Answer 16

k!
