What is the equation of the circle, with center (-4,5) and radius 6 units?

• (x - 4)^2 + (y + 5)^2 = 6

• (x - 4)^2 + (y + 5)^2 = 36

• (x + 4)^2 + (y - 5)^2 = 6

• (x + 4)^2 + (y - 5)^2 = 36

In the equation (x + 2)² + (y - 3)² = 4, the radius of the circle is:

• 4

• 2

• 8

• 16

Write the equation of the circle with center C(4 , -8) and radius = 5

• ( x - 4 )² + ( y + 8 )² = 25

• ( x + 4 )² + ( y - 8 )² = 25

• ( x - 4 )² + ( y - 8 )² = 25

• ( x + 4 )² + ( y - 8 )² = 10

What is the equation for this circle?

• (x + 1)² + (y + 1)² = 9

• x² + y² = 3

• (x - 1)² + (y - 1)² = 9

• (x + 1)² + (y + 1)² = 3

What is the equation of a circle with radius 4 and center (0, 8)?

• x² + (y - 8)² = 16

• (x - 8)² + y² = 4

• x² + (y - 8)² = 4

• x² + (y + 8)² = 16
