Which best describes how to find the length of an arc in a circle?

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
