Write the equation of a circle with center (7, 0) with radius 3.

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 = 5 units

• Center (-4,-3)
  Radius = 25 units

What is the equation of the circle?

Is the point (3 , 5) inside, outside or on the circle with equation x² + y² = 9?

• Inside the circle

• outside the circle

• on the circle

A circle has the equation x² + y² - 8x + 6y - 11 = 0. Write it in standard form.

A circle has the equation x² + y² + 10x - 4y + 20 = 0. Write it in standard form.

• (x-5)² + (y+2)² = 9

• (x+5)² + (y-2)² = 3

• (x+5)² + (y-2)² = 9

• (x+5)² + (y-2)² = 49
