Ellipses and Circles Practice

What are the coordinates of the center and the radius of the circle with equation:
(x - 4)² + (y - 3)² = 25 ?

• Center (4,3)
  Radius = 5 units

• Center (4,3)
  Radius = 25 units

• Center (-4,-3)
  Radius = 25 units

• Center (-4,-3)
  Radius = 5 units

In the equation (x-3)²+(y-2)²=16, the center of the circle is...

• (3,2)

• (-3, -2)

• (-2, -3)

• (2, 3)

• (x - 1)² + (y + 2)² = 2

• (x + 2)² + y² = 4

• x² + (y + 2)² = 4

• x² + (y + 2)² = 2

• Center: (0, 2), a=100, b=25

• Center: (0, 2), a=10, b=5

• Center: (0, -2), a=10, b=5

• Center: (0, 2), a=100, b=25

• Center: (4, -2), a=-16, b=-9

• Center: (4, 2), a=16, b=9

• Center: (-4, -2), a=3, b=4

• Center: (-4, -2), a=4, b=3
