In a circle of any size, what ratio does pi represent?

Pi represents ratio of the circumference of any circle to the diameter of that circle.

Step-by-step explanation:

We are asked to tell what ratio does pi represent in a circle of any size.

We know that all circles are similar as when we divide circumference of circle by its diameter we get same value that is pi.

, where,

C = Circumference of circle

We know that diameter of circle is two times radius, so we can manipulate our equation as:

, where, D represents diameter of the circle.

Let us divide both sides of our equation by D.

Therefore, pi represents ratio of the circumference of any circle to the diameter of that circle.

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
