Question

8. The circle below is centered at the point (5,-2) and has a radius of length 4. Write the equation for the circle.

Answer 1

(x - 5)² + (y + 2)² = 16

Explanation:

Equation of a circle formula: (x - a)² + (y - b)² = r²

where (a, b) is the center of the circle and r is the radius

Given, center = (5, -2) and radius = 4

Substitute this information in the equation of a circle formula.

⇒ Equation of the circle: (x - 5)² + (y + 2)² = 16
