      diameter times pi = circumference


      Ex.


      π = 3.14159265359


      d = 16 > diameter is twice the radius


      r = 8 > radius is half of the diameter


      Calculator:


      16 • π = c  or  16π = c


      c = 50.2654824574 > rounded to nearest tenth is..........


      c = 50.3


      Pencil and paper:


      d = 16


      16 • 3.141 = 50.256 > rounded to nearest tenth is.........


      c = 50.3


      Usually you are told to use 3.14 for pi on paper and pencil.


      d = 16


      16 • 3.14 = 50.24


      c = 50.24
