The center of circle q has coordinates (3,-2) of circle q passes through r(7,1) what is the length of its diameter? (geometry)

the distance between the center and any point on the circle is radius. double that and you get the diameter since diameter is doubled radius.

by distane formula, the radius is

sqrt( (x2-x1)^2 + (y2-y1)^2 ) = sqrt( (3-7)^2 + (-2 -1)^2) = sqrt(25) = 5

the diamter is 10

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
