So the formula is 2pi(r)(h)+2(pi)(r^2)
2(3.14)(40)(17)+2(pi)(40^2)
so then multiply and add it up and you get
about 14,325 1/3 or 14,325.34

Answer: see below
Step-by-step explanation:
The charges is always at least $80 just for the plumber to show up. The, it increases by $60/hour.
We represent cost, c in dollars, as below.
part A --> c = 80 + 60h
where h is the number of hours.
For 3 hours work, c = 80 + 60(3) = 80 + 180 = $260
part B --> $260
I hope this helps.
