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: no solution
Step-by-step explanation:
They have the same slope which means they are parallel lines that will never cross or intersect. This mean that there is no solution
Answer:
Do the Division first.
Step-by-step explanation:
If you remember PEMDAS, or BOMDAS if you prefer, division and multiplication comes before addition and subtraction.
x, in this case, would equal -27. (-27 ÷ 3 = -9) then add 10
(-9 + 10 = 1)
Answer:
3boxes
