Question 448912: A concrete culvert that is 10 m long has
an outside diameter of 1 m and an inside
diameter of 0.8 m. Determine the volume of
concrete required to make the culvert, to
the nearest tenth of a cubic centimetre.

You can put this solution on YOUR website!
The inside volume is
V1+=+pi%2Ar%5E2%2Ah+=+pi%2A0.4%5E2%2A10+=+1.6pi cubic meters
---------------
The outside volume is
V2+=+pi%2Ar%5E2%2Ah+=+pi%2A0.5%5E2%2A10+=+2.5pi cubic meters
V2+-+V1+=+0.9pi cubic meters
1 cubic meter = 1,000,000 cc
Vol = 0.9*piE6 cc
=~ 2827433.4 cc
