Question

A circle with centre at the origin cuts the y-axis at the point (0,5).
(a) Write the coordinates of other two points on this circle
(b) What is the radius of this circle ?
(c) Verify whether the point (4,4) lies on this circle.​

Answer 1

Answer:

Answer. Answer: the equation of circle :(x-h)^2+(y-k)^2=r^2 here ,its centre:(h,k)=(4,5) now, if the circle touches the x axis,then its radius is 5 unit( the point).
