Answer 1

center: (2,3)
radius 5

Answer 2

how did you get that? lol

Answer 3

if the equation is (x-a)^2+(y-b)^2=c^2
then the center is (a,b) and the radius is c

Answer 4

can i ask you another one?

Answer 5

sure

Answer 6

x^2+(y-7)^2=49

Answer 7

that is (x-0)^2+(y-7)^2=7^2
so (0,7) and 7

Answer 8

what about x^2=y^2=1 would it be (0,0) and 1?

Answer 9

x^2+y^2=1 for this yes

Answer 10

yay i got it right! lol thankyou

Answer 11

your welcome
