Density or weight is calculated by mass/volume
The answer depends on what information about the circle is given: area, radius, length and angle of arc, area and angle of sector, etc. In each case, there is a different way to calculate the diameter but, since there is no information on what is known, it is not possible to answer the question.
Circumference = diameter*pi
It is not possible to calculate weight just from length, width and/or height. (These can give you volume and area, but not weight). For weight, you need to know "how heavy it is per this amount of stuff" is - e.g "3 grams per square cm" or "6 tonnes per inch".
Subtract the square of the width from the diameter. The square root of that is the length.
To calculate the weight of a galvanized steel pipe, you need to know the length, diameter, and thickness of the pipe. Use the formula: weight = (outer diameter - thickness) x thickness x 0.02466 x length. This formula assumes the density of steel as 7850 kg/m^3 and the length in meters.
You can't. They are independent of one another. A pipe of a given diameter may have any length, and vice-versa.
To calculate weight or mass when diameter and height are given, you first need to calculate the volume of the object using the formula for the volume of the shape (e.g., cylinder, sphere). Once you have found the volume, you can then calculate the weight or mass by multiplying the volume by the density of the material. Weight can be calculated using the formula Weight = mass x gravity.
You cannot. Diameter and length can, for some particular shapes, give you the volume. But that will not give you the mass unless you know the density of the substance.
The weight of rebar can be calculated using the formula: weight = (diameter^2 * length * 0.006165) kg, where the diameter is in mm and length is in meters. Substituting the given values, the weight of the rebar would be approximately 22.98 kg.
Answer 1It is necessary to assume that the shape is a sphere, since that is the only shape whose volume is determined by only its radius/diameter.Radius = Diameter/2Volume = 4/3*pi*r3 or 1/6*pi*d3Weight = Density*VolumeAnswer 2If you are given length as well as diameter, the object could be in the shape of a cylinder. The formula for the volume of a cylinder is V = (pi)r2h. Use the formulas for radius and weight given in answer 1.
Density or weight is calculated by mass/volume
Radius of a circle = diameter/2
The length of the spiral ring is given by the formula L=N*Pi(D+d)+8d where L=length, N=number of spirals, D=diameter of pile and d=diameter of the bar.
The answer depends on what information about the circle is given: area, radius, length and angle of arc, area and angle of sector, etc. In each case, there is a different way to calculate the diameter but, since there is no information on what is known, it is not possible to answer the question.
