How to calculate round column volume.
+==
No formula given so how can the "answer" be useful? The volume of a round column of radius r and height h is that of any cylinder:
r^2.pi.h.
Calculate the round column shuttering
Multiply column inside diameter by the column's length. Then convert to units you need. The above is not correct.The volume of a column is the circular area of the column multiplied by the length, pi*radius^2*length.
length x width = area
Calculate the area to be covered. (A) Calculate the area per board or pack (B) Divide (B) into (A)
To calculate Cross Sectional Area: Width x Depth

Multiply column inside diameter by the column's length. Then convert to units you need. The above is not correct.The volume of a column is the circular area of the column multiplied by the length, pi*radius^2*length.
A flat round object is a circle. Surface area of a circle = pi*radius squared.
Get the summation of the AREA of all columns and multiply with the effective height.
Surface Area = (Circumference)(Height)* Volume = ∏r2 x Height *If you want to include the top and the bottom in the surface area of the column you have to add the area of the top and bottom. So, the Total Surface Area = [(Circumference)(Height)] + 4(∏)(Radius2)

You cannot. The whole point in describing it as a water column is that it is a body of water that is 2 metres high - WHATEVER the size of its cross sectional area.
To round a number to the nearest hundred, go to the tens column. If it is a 5 or over, round up to the next hundred. If it is a 4 or lower, round down.So in 5465, the tens column has a 6. Therefore you round up to 5500.If you wanted to round 5443 to the nearest hundred, you would round down to 5400 because there is a 4 in the tens column.

Look at the units column (number 8). It greater than 5, so you round up the tens column Answer: 90
the first number after the decimal point is the tenths column; the second after the decimal is the hundredths column To round to nearest tenth, you look at the number in the hundredth column - if it is 5 or greater you round up by one the number in the tenths column; if less than 5 you keep it the same. In this case 0.569 rounds to 0.6
