Hello,
The formula for finding the circumference of a circle is [tex]2 \pi r[/tex] where r is the radius. SO we can plug 4 in for r in this formula because 4 is the radius:[tex]2 \pi 4=8 \pi [/tex]. We are told to use 3.14 for [tex] \pi [/tex] so we get [tex]8(3.14)=25.12[/tex]. Therefore, the circumference is 25.12 meters.
