Question

A carpenter plans to cut a formica to go around the outer edge of a circular table. To find out how long he needs to cut it, he must find the circumference of a circle. If the radius of the table if 2 feet and the constant π is approximately 3.14, how long should he cut the formica

Answer 1

Let's take a look at the situation:

Now, we know that the formula for the circumference of a circle is:

`C=2\pi r`

Using this formula and the data given, we get that:

`\begin{gathered} C=2(3.14)(2) \\ \Rightarrow C=12.56 \end{gathered}`

He sould cut the formica 12.56 ft long.
