Find the circumference of thecircle. Use 3.14 for ti. Do notround your answer.C = [ ? ] feet18 feetEnter the number thatbelongs in the green box.Hint: C = 2tr

Answer 1

The formula for calculating the cricumference of a circle is:

`C=2\pi r`

Given that:

`\begin{gathered} \pi=3.14 \\ r=18ft \end{gathered}`

We substitute the values into the formula, as solve as follows:

`\begin{gathered} C=2\pi r \\ \Rightarrow C=2*3.14*18\text{ =113.04} \\ \Rightarrow C=113.04ft \end{gathered}`

Thus, the circumference of the circle is 113.04ft
