Please help with physics!?

a pipe radius of 0.0100 m carries water at 2.33 m/s. How much time does it take to fill up a 1.00m^3 fish tank? (unit=s)

    BY Q = Av

    =>Q = πr^2 x v

    =>Q = 3.14 x (0.01)^2 x 2.33

    =>Q = 7.32 x 10^-4 m^3/sec

    Let the time to fill 1 m^3 tank is t sec

    =>t = V/Q

    =>t = 1/(7.32 x 10^-4) 

    =>t = 1366.83 sec OR 22 min & 46.83 sec

    flow Q = V*A = 23.3 dm/sec*0.7854*0.2^2 dm^2 = 0.732 liters/sec ..(0.7854 = PI/4)

    time t = V/Q = 1000 liters / 0.732 liters/sec = 1366 sec

    V = v π r^2 t

    then

    t = V / (v π r^2)

    t = 1 / (2.33*3.14*0.01^2) = 1366.8 s = 22 min 47 s
