How many complete tanks of water,each with a capacity of 3 cubic meter are needed to fill an empty cylindrical tank whose height is 3m and base has a radius of 2m?
A.12 B.13 C.14 D.15 E.16

• volume of cylindrical tank=(22/7)*(2*2)*3 cubic meters
  so total water cans with 3 cubic mete capacity needed to fill the tank are=(3.14)*(2*2)*3/3=4*3.14=12.57
  but here asked about complete tanks of water,each with a capacity of 3 cubic meter needed, so answer is 12 only....
  (a) 12

• Volume Of Cylinder -> Pie * r^2 * h
  Pie = 3.14, r = 2, h = 3
  
  3.14 * 2 * 2 * 3 => 37.68
  
  37/68 -> 12.56
  
  We need complete tanks so Answer is 13

• Volume Of Cylinder = Pie * r^2 * h
  
  
  22/7 * 2 * 2 * 3 =37.68
  
  then 37.58/3=12.53
  
  so Answer is 13

• volume of cylinder =3.14*r*r*h.
  let the x no of tanks are required then
  according to give condition:
  3x=3.14*2*2*3 =>12.56 ans is:13
