A vernier caliper should be used to measure the diameter of a steel ball.

13mm diameter & 3100 length pl. give me weight
Area = 1/4*Pi*d2 = 0.25*3.14*162(256)= about 200.963ft2
162 162 = 162 162
DxD/162 this is the formula for finding unit weight of steel
[diameter]^2 / 162 kg 1.580 kg / meter
Formula for steel bar weight per meter = D2/162 where D is diameter of bar
=D^((D^2/162) L) D^2 = Diameter of the rod L = Length of the rod
Weight of MS Round Bar is calculated as ((Diameter in mm)^2)/162.
The unit weight of steel is 7850kg per cubic meter, so the unit weight of different bars can be calculated by multiplying the volume of 1m length of bar with the unit weight of steel.It can also be calculated simply by dividing the square of the diameter of bar in mm by 162.Diameter of bar unit weight calculation.8 0.395kg/m w=8x8/16210 0.617kg/m w=10x10/16212 0.889kg/m w=12x12/16216 1.580kg/m w=16x16/16220 2.469kg/m w=20x20/16225 3.858kg/m w=25x25/162
Circumference = diameter times pi. C = 162 times 3.14159 = 508.938 yards.
2.9876 kg/m is the weight of steel bar of 22 mm dia..and you use formula for other bars as d*d/162 Where d is a diameter of bar in mm.
weight of all steel can be calculated by multiplying unit volume with density.
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.
D2/162
There is no single diameter - there are steel rods of different diameters for different uses.
