    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
