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!
