Circumference of a circle = \(2 \pi r\)

They are all multiplied by each other
r = radius 
we know our radius is 40 
and... \(\pi\) = 3.14 

so we would use this expression 
3.14 x 40 x 2 

As a added bonus ill solve it for you :P
3.14 x 40 x 2 = 251.2 
The circumference of this ice skating rink is 251.2 feet

on ttm the  asnwer is 2 times 40 times circumference                    hint: it will always be 2 numbers time circumference          maek me brainliest pls
