You need the length of the rod to compute the weight.
To do so, you can calculate the volume of the rod, which would be length*Pi*22 multiplied by the density of MS, which is 7.86 g/cm3, or simply 15.72(Pi)*length of the rod
Mildsteel rod 40mm dia. = 9.85 kg per metre. I think that is what you asked.
To calculate the weight of a 40mm diameter and 3mm thickness mild steel (MS) pipe, use the formula for the weight of a hollow cylinder: Weight = Volume × Density. First, calculate the outer diameter (OD = 40mm), inner diameter (ID = 34mm), and then the volume (V = π/4 × (OD² - ID²) × Length). The density of mild steel is approximately 7850 kg/m³. Multiply the volume by the density to find the weight.
Officially, 40mm in diameter. Originally, table tennis balls were officially 38mm in diameter. It wasn't until October 1st, 2000 that the ITTF changed the official ball size from 38mm to 40mm. The reason for the change was to make the game more appealing to spectators by slowing down the ball. There are some recreational ball sizes that are played with for fun such as the 46mm ball (huge!).
30mm x 40mm translates to 3cm x 4cm, which is equivalent to 1.18 inches x 1.57 inches. This size is roughly the dimensions of a standard credit card, though slightly smaller. It is often used for small photographs, labels, or business cards.
40mm is 4cm. There are 100cm in a meter.
There are 4 centimeters in 40mm - 10mm per centimeter.

The weight of a 40mm diameter mild steel (MS) pipe would depend on its length and wall thickness. A general estimate for a 40mm MS pipe with a wall thickness of 3mm would be around 3.27 kilograms per meter.
hey how are u doing i do not kwon the radius of a ping pong ball okay so have a good day
=3.14 * (Diameter of pipe in Mtr. - wall thickness in Mtr. ) * Wall Thickness in Mtr. * 7850
40mm diameter and 17mm tall (average tealight)
The weight of 40mm rebar per meter is approximately 9.87 kilograms (21.76 pounds).
The inside diameter = 40 - 2 x 1.6 = 40 - 3.2 = 36.8 mm
40 mm is 40 mm, a little over 1 1/2".
The recommended tire size for a bicycle with a wheel diameter of 40 622 is typically 700c x 40mm.
The official rules of table tennis state that the ball must be spherical, with a diameter of 40mm.

It means that it has variable magnifcation, from 3 to 9 times larger, and has a front lens that is 40mm in diameter.
