Question

Write the equation of the circle with center (-11,-14) and radius 3.

Answer 1

(x + 11)² + (y + 14)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 ) = (- 11, - 14 ) and r = 3 , then

(x - (- 11) )² + (y - (- 14) )² = 3² , that is

(x + 11)² + (y + 14)² = 9
