There is no single diameter - there are steel rods of different diameters for different uses.
1 metre = 100 cm125 mm = 12.5 cmVolume of a cylinder = (pi) x (radius)2 x (length)Radius = 1/2 of diameter = 6.25 cmVolume = (pi) x (6.25)2 x (100) = 12,271.85 cm3 = 12.272 litres (rounded)
If the bar is circular then it is: pi*radius square
Answer
for density of steel @ 7850 kg/m3 you can use No of bars (12 m long) per ton = (13500 / D2) where D= bar diameter in mm
formula: (R+2t)=D where, R-radius or pipe t-thickness of pipe D-diameter of pipe. by using above formula we get the diameter of a steel pipe, by using vernier caliper
This depends on what type of steel. The density of carbon steel (one of the most common types of steel) is 7.85g/cm3Density = m/vradius of rod = 3.25mm (radius is 1/2 of diameter)3.25mm = .325 cm1 meter = 100cmvolume of cylinder = (pi)(radius)^2(h) = 33.18Density * Volume = mass7.85 * 33.18 = 260.46260.46 grams
The volume change of a sphere can be calculated using the formula V = 4/3 * π * r^3, where r is the radius. The temperature change required to increase the volume can be calculated using the coefficient of thermal expansion of steel. The diameter of the steel ball bearing at 100°C can be calculated using the volume change and the new temperature, considering the change in radius.

To find the volume of a steel marble, you can use the formula for the volume of a sphere, which is V = (4/3)πr^3, where r is the radius of the marble. Measure the diameter of the marble using a caliper, then divide it by 2 to get the radius. Plug the radius into the formula and calculate the volume using the value of π. This will give you the volume of the steel marble in cubic units.

Measure the diameter = d cm. Then radius = d/2 cm and cross sectional area = pi*r2 cm2.Measure the diameter = d cm. Then radius = d/2 cm and cross sectional area = pi*r2 cm2.Measure the diameter = d cm. Then radius = d/2 cm and cross sectional area = pi*r2 cm2.Measure the diameter = d cm. Then radius = d/2 cm and cross sectional area = pi*r2 cm2.
Yes, it will rust unless it is protected with paint, plastic or oil.
Most rebar (steel reinforcement bar) is approximately round. Measure the diameter of the bar, that is, the thickness of the bar. Divide the measurement by 2 to get the radius. Use the formula pi x r2 (3.14 x radius x radius) to get the cross sectional area. The formula works for all measurement units whether they are inches, millimeters, centimeters or others. An alternative is to use (pi x d^2)/4. (3.14x diameter x diameter divided by 4) You do not then need to divide the original diameter.
You can determine the volume of a steel ball bearing by using the formula for the volume of a sphere, V = (4/3) * π * r^3, where r is the radius of the ball bearing. Measure the diameter of the ball bearing and divide it by 2 to calculate the radius, then plug it into the formula to find the volume.
