Volume of cylinder = (pi)(r^2)(h), where 'r' is the radius of the base of the cylinder and 'h' is the height of the cylinder.
So, volume of tank = (pi)(2^2)(3) = 12pi or 12 * 3.14 = 37.6 cubic meters appr.
Therefore, no. of tanks of water required = 37.6/3 = 13 appr.
So, volume of tank = (pi)(2^2)(3) = 12pi or 12 * 3.14 = 37.6 cubic meters appr.
Therefore, no. of tanks of water required = 37.6/3 = 13 appr.
