Please, use the symbol " ^ " to denote exponentiation. At first I had no idea what you meant by 3r2.
You are using the approx. formula A = 3 r^2 to find the area.
The given radius is 4.3 inches. Subst. this value for r in the above equation.
Find A (keeping in mind that it's an approximation).
where is your triangle mate??

We multiply a*a*a, so we can rewrite it as a³. The same with b*b as b².
So, the answer in the simplified form is:
6a³ + 4b²
