Question

helpp!

Answer 1

use phytogorean theorem aka distance formula to find radius

Answer 2

^ you will actually find the diameter because the coordinates given are of the diameter not the radius.

Answer 3

i think radious is 4.2426405

Answer 4

just used the distance formula sqrt((6-12)^2+(7-13.)^2)

Answer 5

half of that result

Answer 6

do you know the other two?

Answer 7

hold on the center you have to use midpoint formula

Answer 8

center is 12, 13.5

Answer 9

(12, 13.5)

Answer 10

(x-h)^2+(y-k)^2=r^2 is the equation of circle where h and k is h,k
so it is
(x-12)^2+(y-13.5)^2=4.24^2
