Answer:

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
