Question

What is the equation for a circle with a radius of 7 and center at (
- 6,2)?

Answer 1

(x + 6)² + (y - 2)² = 49

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 ) = (- 6, 2 ) and r = 7 , then

(x - (- 6) )² + (y - 2)² = 7² , that is

(x + 6)² + (y - 2)² = 49

Answer 2

(x+6) squared + (y-2) squared = 49
