HI  THE CUBIC VOLUME OF A CYLINDER IS    Pi X rad sq x length  SO FOR EXAMPLE

Pi   = 3.14159 or  22 / 7

CYLINDER   10CM RAD X 50CM LG   =    Pi X 10 X 10 X 50  = 3.14159 X 10 X 10 X 50  

= 3.14159 X 5000  = 15707.95 cu cm

HI  YOU CAN NOT CONVERT MTS INTO SQ MTRS UNLESS YOU HAVE ANOTHER DIMENSION

IF YOU MEAN  660 MTRS X 1 MTR THEN THE ANSWER IS 660SQ MTRS OR

660 MTRS X 7MTRS = 4620 SQ MTRS

I HOPE THIS HELPS

HI    THE CIRCUMFERANCE OF A CIRCLE IS  Pi x D  =  22/7 X 4 KEEP YOUR DIMENSIONS TO FT AS ITS EASIER

THEREFORE THE TOTAL VOLUME OF YOUR PIPE IS   22/7 X 4 X 1/3 X 20 = 84 cu ft approx

DEPENDING ON YOUR CONCRETE PIPE MIX SAY  150 lbs per cu ft

THIS GIVES   APPROX  12600LBS  = APPROX 6 IMP TONS

Concrete, Asphalt 140 pounds/cubic foot
Concrete, Gravel 150 pounds/cubic foot
Concrete, Limestone w/Portland 148 pounds/cubic foot

AS COLLEEN SUGESTS YOU WOULD BE BEST CONTACTING A MANUFACTURER AS THERE ARE VARIOUS TYPES OF PIPE AVAILABLE EG STANDARD, REINFORCED, LIGTWEIGHT ETC

HOPE THIS GIVES YOU SOME IDEA ANYWAY
