find diameter to the nearest tenth
A.35.2mm
b.36.2mm
c.37.2mm
d.38.2mm

  • math -

    C = pi * d

  • math -

    so it c

  • math -

    You already know c which is the circumference.

    To find the diameter, use this formula:

    d = C / pi

  • math -

    what do you mean i don't get it

  • math -

    diameter = 110.6 / 3.14

    d = ?

  • math -

    Right.
