Answer:
Diameter of pipe = D = 64mm
cross sectional Area of pipe= A = pi * (D/2)^2 = pi * (32)^2 = 1024pi mm^2
Discharge Rate of water = v = 2.05 mm/s
Volume of Cylinder = V = pi * (D/2)^2 * h = pi * (38)^2 * 2300 = 3321200pi mm^3
(Area of pipe)*(Rate) = (Volume) / (Time)
Time = T = (Volume) / [(Area of pipe)*(Rate)]
= (3321200pi)/(1024pi * 2.05)
= 1582.126524s
Angle B = 68 degrees
Using the Law of Sines
b / sin(B) = c / sin (C)
b = sin (68) * c / sin (49)
b = 0.92718 * 3 / 0.75471
b =

Answer:
$24.09
Step-by-step explanation:
you do 984.20-381.80=602.4
then divide 602.4 by 1/4
which 1/4=25.
then you get $24.09
-7 is correct because a negative plus a negative is always a negative
