Circumference of a circle =
They are all multiplied by each other
r = radius
we know our radius is 40
and...
= 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
Answer:
I think u have to put the interest rate so we have more information
You get a complex fraction and you then have to "copy, dot, flop"
For example, (1/2)/5
To solve this, you would change it to 1/2 x 1/5 to get .1
