Question

Center is (5,3) and the radius is 3; what is the equation? (x - h)^2 + (y - k)^2 = r^2

this is about equations of circles​

Answer 1

(x - 5)² + (y - 3)² = 9

Explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k ) = (5, 3 ) and r = 3 , then

(x - 5)² + (y - 3)² = 3² , that is

(x - 5)² + (y - 3)² = 9 ← equation of circle
