a cylindrical water tank is 4m high.if the radius of base is 15 meter.find the volume of the tank.

Sagot :

V = Area of base X Height
  since its base is a circle so you can calculate for its area given the radius..
  Area of base = pi X r^2
                    = pi X 15^2
                     = 225pi
 V = 225pi X 4
 V = 2827.43 cubic meters
