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
Fudgin [204]

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.
