The answer is about 43.9 and if you have to round 44.

Step-by-step explanation:

To find circumference, you need the equasion . To break it down, 2 multiplied by pi then multiplied by the radius. The radius is 7in because the length line on the side goes from the middle, then to the edge. This matches the description of radius. So we take the radius, then multiply it by pi then multiply it by 2.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
