Answer:

C = 2pi mm or approximately 6.28 mm

Step-by-step explanation:

The circumference of a circle is given by

C = 2 * pi * r

C = 2 * pi *1

C = 2pi

We can approximate pi by 3.14

C = 2*3.14

C =6.28 mm

Answer:

The circle's circumference is 2 pi ml

Step-by-step explanation:

The formula for the circumference of a circle is 2[tex]\pi[/tex]r, or diameter times pi.

In this case, we simply plug into the equation. Using the formula 2[tex]\pi[/tex]r, we get 2(1)[tex]\pi[/tex], or 2[tex]\pi ml[/tex]
