(0.45/2)2 x pi x 2 = 1/3rd of a cubic meter
It depends on the depth to which the area is filled.

To calculate the volume of concrete needed to fill a hole with a diameter of 12 inches and a depth of 24 inches, first convert the dimensions to feet: the diameter is 1 foot and the depth is 2 feet. The radius is 0.5 feet. Using the formula for the volume of a cylinder (V = πr²h), the volume is approximately 3.14 × (0.5)² × 2 = 1.57 cubic feet. Therefore, you need about 1.57 cubic feet of concrete to fill the hole.
Approx 10.3 US gallons.
I'll make the assumption that 150 is meant to be metres. 150x6 is 900, x 2.5 is 2250
You can use a concrete crack filler to fill concrete cracks.
A cubic meter of concrete is equivalent to 1,000 liters. An 8-inch form has a cross-sectional area of approximately 0.44 square meters (since 8 inches is about 0.203 meters). Therefore, a cubic meter of concrete would fill an 8-inch form for about 2.27 meters in length (1,000 liters / 0.44 square meters).
To calculate the amount of concrete needed to fill a 12-inch diameter hole that is 18 inches deep, first convert the measurements to feet: the diameter is 1 foot and the depth is 1.5 feet. The volume of a cylinder is given by the formula V = πr²h. The radius (r) is 0.5 feet, so the volume is approximately π(0.5)²(1.5) = about 1.18 cubic feet. Thus, you would need roughly 1.18 cubic feet of concrete to fill the hole.
You can use a concrete patching compound or a concrete caulk to fill in cracks in concrete. These products are specifically designed to repair and seal cracks in concrete surfaces.
We need to know the dimensions of the tube. The diameter AND the length of the tube. It takes o.465 yards per foot of length for a tube 4 feet in diameter. .
To fill 0.2 cubic meters, you will need about 21.6 bags. According to the site at the related link, a 20 kg or 40 lb bag of premixed concrete should fill an area of 1/3 cubic foot, which is 1/106th of a cubic meter. There is also a separate estimate of 108 20-kg bags per cubic meter, which provides essentially the same result.
The volume in the pipe is pi times diameter squared/4 times the length. Eight inch diameter = 2/3 ft so volume is 59.31 cubic feet. Since 27 cu ft = 1 yard then that is 59.31/27 = 2.2 yards of concrete
