Equation of Circle Given Center and Radius

Find the equation of the circle:
center (-2,-7), radius is 3

• (x + 2)² + (y + 7)² = 3

• (x - 2)² + (y - 7)² = 9

• (x + 2)² + (y + 7)² = 9

• (x - 2)² + (y - 7)² = 3

The point (-5,6) is on a circle with center (-1,3) write the equation of the circle (hint: remember distance between any point on the circle and the center is the radius length!)

• (x+1)² + (y-3)²= 4000

• (x+5)² + (y-0)²= 25

• (x+1)² + (y-3)²= 25

• (x-1)² + (y+3)²= 25
