Answer 2

find the circumference diameter=84cm 3use 3.14 for pie

Answer 3

Ok
This is the formula used to find the circumference
\[\huge~\rm~\bf C=2 \pi~r\]
But first we need to find the radius; the radius is HALF of the diameter
\[\huge~\rm~\bf~84 \div 2 =? \]

Answer 4

42

Answer 5

Good! :)
Now all we do is simply substitute the values into the formula
\[\huge~\rm~\bf ~C=(2)(3.14)(42)\]
Solve for C
