If I could see the photo I could help you answer the question
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.
An acre is 43,560 ft² because the customary system hates you.
Let's find out how many square feet the parcel is so we can convert it into acres.
The area of a rectangle is its base times its height.
A = bh
A = 234 ft * 878 ft
A = 205,452 ft²
Divide by 43,560.
A ≈ <span>4.7165 acres. (round as needed)</span>
