Answer:
C
Step-by-step explanation:
First, get the radius, 2.2*3.14 is 6.908. Then, multiply by 18, 6.908*18 is 124.344.
I am unsure about the very last problem but I can help with the first two
1) (y+1)+4
If we combine the numbers 1 and 4, we get +5 and can isolate the numbers from the variable.
This would give us

2) (6*r)*7
remember that we do not have to explicitly state 6*r
Instead, we can write it as 6r
this helps us get rid of the parentheses
now we can write it as

I hope this helps!:)
