Question

If the radius is 7 feet and the diameter is 14 feet what is the circumference

Answer 1

The formula for the circumference of a circle is
`2\pi d`. Substituting d = 14 into this gives us
`28\pi \text{ feet}`.

Simplifying using
`3.14` as
`\pi` gives us
`3.14 \cdot 28 = 87.92 \text{ feet}`.

Simplifying using
`3.14159` as
`\pi` gives us
`87.96452 \text{ feet}`.

Simplifying using
`(22)/(7)` as
`\pi` gives us
`88 \text{ feet}`.

Hope this helps! :)
