It's the first one. If you need any help with graphs, I suggest going on desmos.com
A: 5^2*pi = 25pi =~ 78.5375, 10*5*2*pi = 100pi =~ 314.15, 314.15+2(78.5375) = 471.23 cm^2
b: 4*0.5*1.5 = 3, 6*4 = 24, 6*2.5 = 15.5, 15.5*2 + 3*2 + 24 = 61m^2
c: 5.2*3.5 = 18.2, 2.4*3.5 = 8.4, 2.4*5.2 = 12.48, 12.48*2 + 8.4*2 + 18.2*2 = 78.16ft^2
A bit late but hope it helps

Answer:
point
Step-by-step explanation:
I looked it up
Hello from MrBillDoesMath!
Answer:
1) 70
2) 14
Discussion:
The order of math operations is 1) Parentheses, 2) Exponents, 3) Multiplication and Division (from left to right), and 4) Addition and Subtraction (from left to right)
Using this for 1)
3^2*2^3-(10-2)÷4 =
(3^2) * (2^3) - (10 -2)/4 =
9 * 8 - (8/4) =
72 - 2 =
70
For 2)
8 sqrt(16) - 6 sqrt (9) =
8 * 4 - 6*3 =
32 - 18 =
14
Thank you,
MrB
