Ineed your because i do not understand that i have to find the diameter and the radius of a circle 3.14 • 1.5 • 1.5
2) 3.14 • 1.5 • 1.5
3) 3.14• 1•1
4) 3.14•6•6
5)3.14•2•2
6)3.14•1.5.1.5

and the other is the area 3.14•3
2) 3.14•1.25
3) 3.14•2
4) 3.14•12
5) 3.14•4
6) 3.14•3

Step-by-step explanation:

If you are given  3.14 · 1.5 · 1.5, you actually have 3.14 · 1.5²

If you match this up to the area-of-a-circle formula A = πr²

you can see right away that r = 1.5.  If r = 1.5, d = 2(1.5) = 3.0

I do not quite understand what you were trying to present in your

"And the other is the area 3.14•3

2) 3.14•1.25" so am unable to help you with it.

both equations and proportions are better.
