False.
The volume of a cylinder is how much space it takes up INSIDE. You would use volume to measure how much you can put something inside (like water)
Surface area measures the OUTSIDE of a shape. In this case, you'd use surface area to determine how much paper he needs.

Better deal normlly means the rate that cost less
rate=cost/amount
9=cost and 3/4 bushel = amount for one store
3/4=0.75
9/0.75=12/1 aka $12/1bushel
9 =cost and 2/3 bushel =amount for another
2/3=about 0.66666
9/0.66666=13.5/1 aka $13.5/1 bushell
compare
12 dollars per bushe vs 13.5 dollar per bushel
12 is cheaper
therefor $9 For 3/4 bushel is better deal
Time = distance / rate
time = 290 / rate
The answer would be 390+ 390 =780
