hey im new here so im not sure where to post this, but im pretty sure this is a basic question that i cant remember. so if anyone could help me, id be really grateful cos i have an exam coming up this week n am so lost as to what im doing. Heres the question;
the diagram shows the circle (x-2)squared + (y-2)squared =4 with centre C, touching the x axis at a and y axis at b
i) state the co ordinates of C,A and B

theres more to it but im just hoping if someone can help me answer the question i can do the rest. sori theres no diagram, but its just an axis with a circle touching both the x and y axis and point C in the middle as the centre.

A: (2,0)

B: (0,2)

C: (2,2)

C is the centre of the circle, and as such is (2,2)
A is found when y = 0
B is found when x = 0

Hope that helps
