Question

Write the equation of the circle centered at (-4,3) with a radius of 7

Answer 1

Answer:

(x + 4)² + (y - 3)² = 49

Step-by-step 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) = (- 4, 3) and r = 7 , thus

(x - (- 4))² + (y - 3)² = 7² , that is

(x + 4)² + (y - 3)² = 49
