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.
Answer:
I think Question (a) is 11748 m and Question (b) is 32364
Step-by-step explanation:
Because I Just divided the number of 7031 m square by 79 in Question (a) and I Just multiplied the number of 348 m by 93 but I am not sure It's correct or not
I hope It's helpful
