A section of concrete pipe 30m long has an inside diameter of 1.2m and an outside diameter of 1.8m. what is the volume of concre
te in this section of pipe?
1 answer:
length of pipe= 30m
Inside dia. = 1.2m
Outside dia. = 1.8m
Volume of concrete= (outside dia. - inside dia.)h
V= (pi)
v= [(3.14*0.9*0.9)-(3.14*0.6*0.6)]30
v= (3.3534-1.1304)30
v=(2.233)30 = 66.690m cube
since it's volume the answer 66.690 is in cubic meters.

It should be B. That would make it to where the circle touches the y axis at (6,0). I hope this helps.
1500 volume x 1 per minute

24 hours or 1440 minutes
1500/1440 = 1.04
Flow Rate is 1.04
Time for job = 3/4 hr/job = 45 minutes to do the whole job.
