Okay, well to start with, the equation for the circumference of a circle is C = 2(pi)r, and since we are given the radius (14 7/8ft) we can easily plug it in to this equation.
Now, for simplicity, I am going to put the fraction into decimal form.
I believe it is distributive because you are finding the products. Yes, the numbers are mixed up but the parenthesis often involve distributive property.
