Circles : 3

    Cards (16)

    • Circle
      A closed curve where all points are equidistant from a fixed point called the center
    • Sketching the graph of a circle
      1. Identify the center
      2. Determine the radius
      3. Plot the points on the graph
    • Equation of a circle
      x^2 + y^2 = r^2, where (h,k) is the center and r is the radius
    • Slope of a line
      • Calculated as (y2 - y1) / (x2 - x1)
    • Finding the standard equation of a circle
      1. Find the midpoint of the diameter
      2. Use the distance formula to find the radius
      3. Substitute into the standard form equation
    • The center of the circle is the midpoint of the diameter
    • The radius of the circle is half the length of the diameter
    • Possible coordinates of an epicenter
      • (3.31, 1)
      • (-3.31, 1)
      • (5.20, 1)
      • (-5.20, 1)
