1. ## cylinder

Hey! - Im Ady, i need your help guys! I need more clarification than help, right... i need to figure out the volume of cylinder so,: Diameter - 10.5m Length - 1695m so we know that volume of cylinder = pi x (radius of base^2) x height or V = pir^2h .........Solution? r = 5.25^2m v = pi x 5.25 x 1695 = pi x 27.56 x1695 = 146,766.0164m^3 This is right? Cheers guys!

V = pi r^2 h = pi (5.25)^2 1695 ~= 146770.3 cubic metres

3. thankyou, so what am i doing wrong? i cant get your answer? i can only get mine, where am i going wrong

It doesn't look to me like you did anything wrong. I suspect the only difference between your calculation and CaptainBlack's was, perhaps, the number of digits of $\displaystyle \pi$ you used. They are both the same answer to the required number of significant digits.

5. i have figured it...how bizzare! In terms of a Cylinder, the 'length' could this also be termed as 'depth' ?

It all depends on what axis you are "looking down."
