Question

Enter the equation of the circle described below.
Center (5,2), radius = 3

Answer 1

(x - 5)² + (y - 2)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 the radius

Here (h, k ) = (5, 2 ) and r = 3 , then

(x - 5)² + (y - 2)² = 3² , that is

(x - 5)² + (y - 2)² = 9
