Set up a pair of proportional ratios...
a/(2πr)=α/360
a=(πrα)/180, we are given that r=12 and α=36° so
a=432π/180 in
a=12π/5 in
a=2.4π in
a≈7.54 in (to nearest one-hundredth of an inch)

Answer:
1. If x=5, 3*5=15, 15*15=225 + y (3) = 228.
2. If y=4, then 10*4 = 40, 4^2 is 16, so 40 + 16 is 56.
I might be wrong, but the first one you answered, x^2, x= 1/2, I think that is wrong. when something is squared, you don't go, "Oh, well since 1/2 equals 1, that's the answer." The way to figure out something like this is... 1/2 times 1/2, which is .25, or 1/4. Another example: 3^5 . The way to find this out is 3*3*3*3*3 = 243. But you don't go 3*5, because that answer would be 15, which is not correct.
