@Mehek14 sorry I keep tagging you but you're so helpful XD

You need to find the volume first, then use 
totalcost=cost/\inc3×volume

to find th evolume, use 
V=πr2h

Sorry I'm not really good at reading formulas can you make it more simple XD

anonymous · Answer

so in your case, r=9, h=9.5, cost/inch3=0.09. rest should be easy

So would I do 9*9.5?

anonymous · Answer

i would believe so

twizttiez · Answer

Okay so I got 85.5 then I multiplied that by 0.09 and got 7.695 and I rounded it to 7 would that be correct @Siri15 @Mehek14

Here's what I got:
π x $9^2$ x 9.5 = 2416.23
0.09 x 2416.23 = 217.46
@Siri15 you just copy pasted from another post -_-
