Question

Wha is the equation of a circle with center (-3, -5) and radius 4

Answer 1

(x + 3)² + (y – 5)² = 16

Explanation:

Equation of a circle is (x – h)² + (y – k)² = r²

h is the x of the point, so -h = 3

k is the y of the point, so -k = 5

r is the radius so r² = 4² = 16

so

(x + 3)² + (y – 5)² = 16
