Answer:
area of semicircle only = 113.43 mm²
total area = 185.43 mm²
Step-by-step explanation:
(8.5²)(π)(0.5) = 113.43 mm²
(12)(12)(.5) = 72 mm²
72 + 113.43 = 185.43 mm²
Volume of a cone, V = πr^2h/3
r = Sqrt 3V/πh = Sqrt [(58.9*3)/(3.14*9)] = 2.5 cm, minimum
Surface area, A = πr [r+ Sqrt (h^2+r^2)] = 3.14*2.5*[2.5+ Sqrt (9^2+2.5^2)] = 92.95 cm^2
Therefore, minimum amount of paper required is 92.95 cm^2

Answer: Assuming the plumber will round up the hours, the answer is 335.
Step-by-step explanation:
You can use this equasion to solve the problem: 75+52x=c
In this case, x would equal the number of hours he would work and c would represent the final cost.
Basically, you can just multiply the hourly cost by the hours he works and then add the service fee. Hope this helped!
