Answer:
(x – h)² + (y – v)² = r².
Explanation:
Given : A circle with a radius of r and center at (h,v).
To find : which of the following is the equation for a circle .
Solution : We have given radius = r center = ( h ,v) .
Standard form of circle : (x – h)² + (y – k)² = r².
Where, center ( h ,k ) ,radius = r.
On plugging the values in standard equation
(x – h)² + (y – v)² = r².
Therefore, equation of circle (x – h)² + (y – v)² = r².
