Answer:
(11-h)^2+ (0-k)^2=121
Step-by-step explanation:
(x−h)^2+(y−k^)2=r^2. this is formula for standard form I think
plug in :)
(11-h)^2+ (0-k)^2=11^2(equals 121)
the distance of the circle is 22 because if you sketch this out, the distance between the two endpoints is 22 if you count it out.This means the radius is 11 since diameter is 22
sorry if this is wrong but hope it helps
