If the diameter is 25 then the radius must be 12.5
The number that is 3000 more than 4850 can be found by adding 3000 to 4850. Therefore, the number is 7850.
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
Use steel density of 7850 kg / cubic metre, express all dimensions in metres. > volume = 1 * 1 * 0.02 = 0.02 cubic metres, then: 0.02 cubic metres @ 7850 kg / cubic metre = ( 0.02 * 7850 ) 157 kg
The density of steel is 7850kg/m3 so a 1m2 of 1mm sheet would weigh 7850 x 0.001 = 7.85kg
Formula for sphere volume: 4/3πr³ Plug in 18 for r; the volume is 24429 cm³. Density of iron: 7850 kg/m³ 24429 cm³ • 7850 kg/m³ = 191.76765 kg
7850 sq ft. Formula is pi x R squared. Diameter of 100 means Radius (r) is 50. 50 squared (multiplied by itself) is 25000. Multiply THAT by the value of pi- or 3.14, and you get 7850 sq ft.
To find the radius of a circle given its area, you can use the formula A = πr^2, where A is the area and r is the radius. In this case, if the area is 7850, you would set up the equation as 7850 = πr^2. To solve for r, you would divide both sides by π and then take the square root, giving you the radius of the circle.
The radius would be 49.987 yards.
To find the area of a conductor with a diameter of 100 mils, first convert the diameter to radius by dividing by 2, resulting in a radius of 50 mils. The area ( A ) can be calculated using the formula for the area of a circle: ( A = \pi r^2 ). Thus, the area is approximately ( A \approx 3.14 \times (50 \text{ mils})^2 ), which equals about 7850 square mils.
To find the distance across a circle (the diameter) when you know the area, you can use the formula for the area of a circle, ( A = \pi r^2 ). Given that the area is 7,850 square yards, you can rearrange the formula to find the radius: ( r = \sqrt{\frac{A}{\pi}} ). Once you have the radius, the diameter is twice the radius: ( d = 2r ). Calculating this gives a diameter of approximately 100 yards.
To calculate the weight of a round bar, you can use the formula: [ \text{Weight} = \text{Volume} \times \text{Density} ] First, calculate the volume using the formula for the volume of a cylinder: [ \text{Volume} = \pi \times r^2 \times h ] where ( r ) is the radius (diameter/2) and ( h ) is the length. For a diameter of 35 mm, the radius is 17.5 mm, and for a length of 106 mm, the volume is ( \pi \times (17.5^2) \times 106 ) (in cubic millimeters). Finally, convert the volume to cubic meters and multiply by the density of the material (e.g., steel is approximately 7850 kg/m³) to get the weight in kilograms.
Density = mass/volumeThe unit weight of steel is 7850 kg/m3volume of bar = (πd2/4)*Lhence mass = ((πd2/4)*L)*7850= ((3.14 *d2/4)*1)*7850 for unit length= 0.785*d2*7850= 6162.25 d2 if d is in metersor d2 /162 if d is in mm.By putting the value of diameter of rod, you can calculate the unit weight of any size tmt bar.
The density of steel is around 7850 kg / m3 therefore to find the weight of the steel rod we need to know it's volume.A rod is more commonly described as a cylinder in geometry which has a volume equal to the following:Pi x r2 x hWherer = radius of cylinder (m)h = height of cylinder (m)Volume = Pi x (0.02 x 0.02) x 1Volume = 0.00125 m3Therefore the mass of the rod = 0.00125 x 7850Mass = 9.81 kgWeight = 9.81 x 9.81Weight of rod = 96.2 Newtons
7850 meters = About 5 miles (4.87776386).
Answer: 7850 acres = 12.2656 mi²
To calculate the weight of the steel rod, you first need to find the volume using the formula for the volume of a cylinder (V = πr^2h, where r is the radius and h is the height). Then, you can calculate the weight by multiplying the volume by the density of steel, typically around 7850 kg/m^3. Finally, convert the volume into meters before calculating the weight to ensure consistent units.
Density = mass/volumeThe unit weight of steel is 7850 kg/m3volume of bar = (πd2/4)*Lhence mass = ((πd2/4)*L)*7850= ((3.14 *d2/4)*1)*7850 for unit length= 0.785*d2*7850= 6162.25 d2 if d is in metersor d2 /162 if d is in mm.By putting the value of diameter of rod, you can calculate the unit weight of any size tmt bar.
