Answer :
We need to find the circumference of a circle given diameter 3 cm.
The formula for the circumference of a circle is:
[tex]C=\pi d[/tex]Where
C is the circumference
d is the diameter
We are already given the diameter, so substituting it back, we have:
[tex]\begin{gathered} C=\pi d \\ C=\pi(3) \\ C=3\pi \end{gathered}[/tex]Since π is "3.14", we have:
[tex]\begin{gathered} C=3\pi \\ C=3\times3.14 \\ C=9.42 \end{gathered}[/tex]The Circumference is:
9.42 centimeters
