Question

What is the approximate diameter of the largest Circle she can make

Answer 1

We have that the circumference of a circle can be represented with the following equation:

`C=\pi d`

where d represents the diameter of the circle.

In this case, we have a circle of circumference C = 30 ft made with the lights, then, using the equation and solving for d, assuming that pi equals 3.14, we get:

`\begin{gathered} 30=(3.14)d \\ \Rightarrow d=(30)/(3.14)=9.55\approx10ft \end{gathered}`

therefore, the approximate diameter of the largest circle is 10 ft
