Question 1153614: A fuel storage tank consists of a cylinder with a radius 1.25m and length 7.20m, with hemispheres of radius 1.25m at each end. Determine the cost to cover the tank with 2 coats of paint. One can of paint costs $34.99 and covers an area of 29m2 Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! A fuel storage tank consists of a cylinder with a radius 1.25m and length 7.20m, with hemispheres of radius 1.25m at each end. Determine the cost to cover the tank with 2 coats of paint. One can of paint costs $34.99 and covers an area of 29m2
===============
3*34.99 = $104.97 --- you can't buy part of a can of paint.
===================
If 2 cans are needed for the 1st coat, then you have to buy 3 cans for it.
If you can't use part of a can for the 2nd coat, then you have to buy 3 cans for it.
---> a total of 6 cans.
6*$34.99 = 209.94
===============================
A poorly worded problem, IMO.
