Question

When it gets hot, children play in Burlington's circular water fountain. According to the architectural plans, it has a circumference of 119.32 meters. What is the fountain's radius?

Answer 1

Circumference of a circle formula

`C=2\pi r`

where r is the radius of the circle.

Substituting with C = 119.32 meters and solving for r:

`\begin{gathered} 119.32=2\pi r \\ (119.32)/(2\pi)=(2\pi r)/(2\pi) \\ 19\text{ meters }\approx r \end{gathered}`
