Properties of Circles

  1. What is the circumference formula for circles?
    • chart?chf=bg,s,00000000&cht=tx&chl=d%5Cpi&chs=40x28 or chart?chf=bg,s,00000000&cht=tx&chl=2%5Cpi%20r&chs=56x28
    • where d is diameter, and r is radius.
  2. Formula for the area of a circle.
    A= chart?chf=bg,s,00000000&cht=tx&chl=%5Cpi%20r%5E2&chs=54x28
  3. What do you do when you want to find the exact area of a circle?
    First, you square the value of the radius. Then, you do NOT multiply chart?chf=bg,s,00000000&cht=tx&chl=%5Cpi&chs=22x20
  4. What do you do when you want to find the approximate area of a circle?
    First, square the value of the radius. Then, multiply chart?chf=bg,s,00000000&cht=tx&chl=%5Cpi&chs=22x20
  5. What is the approximate value of chart?chf=bg,s,00000000&cht=tx&chl=%5Cpi&chs=22x20?
    3.14
  6. How do you name a circle?
    By its center point
