_________________________

➜ First you need to set up the formula:

  • Formula:
    C=2π
    *r

  • 2π
    *7=43.9822971503

➜ Round:

  • To round, look at the number in the tenths place:
    9. Now look to the right of that number, In this case it's an
    8. So if the number is greater than or equal to

  • So when we round
    43.9822971503 we get:

- Thousandth:
43.982

- Hundredth:
43.98

- Tenth:
44.0

_________________________

So based on the above work we can conclude that the circumfrence of the circle is:

  • Exact Form:
    43.9822971503
