Identify If a Point Is on a Circle

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

What is the center of a circle with equation (x+4)² + y² = 5?

• (-4, 0)
• (4, 0)
• (4, 1)
• (-4, 1)

The point (-5,6) is on a circle with center (-1,3). Write the equation of the circle.

• (x+1)²+(y-3)²=25
• (x+1)²+(y-3)²=5
• (x-1)²+(y+3)²=5
• (x-1)²+(y+3)²=25

Determine whether the  point (5,-5) is on, inside, or outside the circle defined by x²+y²=34

• On
• Inside
• Outside
• Off the graph!

Determine whether the  point (5,-3) is on, inside, or outside the circle defined by x²+y²=34

• On
• Inside
• Outside
• Off the graph!

Does the point (6,3)  lie inside, on, or outside the circle
(x+2)² + (y+2)² = 85

• inside
• on
• outside

Does the point (4,5)  lie inside, on, or outside the circle
(x+2)² + (y+2)² = 85

• inside
• on
• outside

What is the center of the circle given by the equation (x - 7)² + (y + 3)² = 25

• (-7,3)

• (7,-3)

• (3,-7)

• (-3,7)

Write an equation of the circle for the given information. Center (7,-4) and radius 6 units.

• (x-7)² + (y+4)² = 36

• (x+7)² + (y+4)² = 36

• (x-7)² + (y+4)² = 6

• (x-7)² + (y-4)² = 36

• (x+1)² + (y +1)² = 3

• (x+1)² + (y -1)² = 3

• (x+1)² + (y +1)² = 9

• (x-1)² + (y -1)² = 9
