Question

Find the equation of the circle whose center and radius are given.
center (5,6), radius = 3

Answer 1

(x - 5)² + (y - 6)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, 6) and r = 3, thus

(x - 5)² + (y - 6)² = 9 ← equation of circle
