Question

Write the equation of the circle with the given information.
Center: (2,8)
Radius: 3

Answer 1

(x - 2)² + (y - 8)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 ) = (2, 8 ) and r = 3 , then

(x - 2)² + (y - 8)² = 3² , that is

(x - 2)² + (y - 8)² = 9
