Answer:
4.2
Step-by-step explanation:
First you use the cylinder formula 2 times pi times radius squared plus 2 times pi times radius times height. If you plug it in which is 2 times .8 squared plus 2 times pi times .8 times 1.8 you get 13.0689. Then you multiply that by three because there are three tanks and you get 39.2067. After that you subtract 35 because there are seven tins of paint and they each cover five meters and you get 4.2067. The final answer is No he doesn't have enough paint to cover it completely because he has 4.2 meters left to cover (don't forget to round 4.2067). Here is the work sorry about the picture I took it with my laptop not my phone sorry :). But I hope this helps.
