What is the circumference of the following circle? units Show Calculator

Answer 1

The circunference C is given by

`C=2\pi\cdot r`

where Pi is given by

`\pi=3.1416`

and r (radius) is equal to 1 units (in our case).

By substituting these values into the circunference formula, we get

`C=2(3.1416)(1)`

which gives

`C=6.2832`

that is, the circunferece is equal to 6.2832 units.
