Question

equation of circle

Answer 1

the equation of a circle is X^2+y^2 =r^2

Answer 2

(x-a)^2+(y-b)^2=r^2

Answer 3

so A then?

Answer 4

you have (-10,6) so a=-10 and = 6

Answer 5

because radius squared is 64

Answer 6

no

Answer 7

oh

Answer 8

(x-(-10)^2 +(y-(6))^2=8^2

Answer 9

6 - b right? and -10 = a?

Answer 10

(x+10)^2(y-6)^2=64

Answer 11

yes a =-10 but if you put it in the equation which is (x-a)^2 then (x-(-10))^2 would (x+10)^2

Answer 12

the same for y

Answer 13

then the answer will be....

Answer 14

c?

Answer 15

yes
