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).
Answer:
Step-by-step explanation:
look at each picture to see what they are stating is the same in each of the triangles... the marks thur the lines means they are the same length, or the double or triple arcs in the angles means those are the same. so if there are two sides that are the same... you can say SSS , if there are two angles that are the same you can say ASA . the one where there is one side and one angle the same you can say SAS .... hmmm kinda get it?
So you just plug in 3 into variable p in the equation. C=12(3)+5
C=26+5
C=31
