Circumference Formula: C = πd

• d is diameter

Step-by-step explanation:

Step 1: Define

C = 3.14 units

Step 2: Solve for d

1. Substitute in variable [Circumference Formula]:                                          $3.14 = \pi d$
2. [Division Property of Equality] Isolate d:                                                       $1 = d$
3. Rewrite:                                                                                                           $\displaystyle d = 1$
