YES THERE IS SO HOW DID YOU WORK OUT YOUR PROBLEM HOW DID YOU CAME UP WITH THAT ANSWER?
Geometry
Well you see in my math work it ask me to use 3.14 for pie. and the answer that I got was one my choices so I'm assuming that I did it correct
Geometry
Ok so can you please check if I did it correct v=pi*r^2*h v=pi*27^2*3=2187+3.14=6867.18 ft^3 and if I round it of to the nearest tenth it will be 6867.3 ft^3

CAN SOME ONE JUST HELP ME HOW TO START IT OF PLEASE.. The foundation for a cylindrical water tank is a cylinder 27 ft in diameter and 3 ft high. How many cubic ft of concrete are needed to build the foundation?
Geometry
thank you
Geometry
Consider the experiment of rolling a single die what is the probability of rolling an odd number? I came up with 0.5,even odds as there are 3 odd and 3 even numbers so the prob. is 0.5 Did I do this correct.
Geometry
So by looking at the website that you emailed me it's congruent correct.
