You can solve this in two steps. (1) Calculate the ball's volume. Use the formula for a sphere, and remember that the radius is 1/2 the diameter. Convert the result it either to cubic decimeters (= liters) or to cubic meters. (2) Divide the mass by the volume.

The volume of a sphere is given by V = (4/3)πr^3, where r is the radius (half of the diameter). Calculate the radius (3.75mm) and convert it to meters (0.00375m). Convert the mass to kg (0.001675kg). Using the formula for density (ρ = m/V), where ρ is density, m is mass, and V is volume, you can calculate the density of the steel ball.

What are the weights of 50mm 60mm and 75mm dia hollow m s pipe?
The weight of a hollow MS (mild steel) pipe is determined by its dimensions and material density. You can calculate the weight using the formula: weight (kg) = (outer diameter - inner diameter) x inner diameter x length x density of MS. The specific density of MS used will affect the weight of the pipe.
What is the weight of 75x10 mm gi flat per meter length?
The weight of a GI flat with dimensions 75x10 mm per meter length can be calculated as follows: 75mm x 10mm x 0.00785 (density of steel) = 5.8875 kg/meter.
What is a piace of glass that you put under a microscope?
A microscope slide is a thin, flat piece of glass that specimens are placed on for viewing under a microscope. It usually has dimensions around 25mm x 75mm and is used to hold the specimen securely and provide a clear background for observation.
Can someone help you with this question. Calculate the force that would be overcome by a 150mm diameter piston with a maximum operating pressure of 60 bar?
To calculate the force, you can use the formula: Force = Pressure x Area. First, convert the diameter of the piston to radius (75mm). Then, calculate the area of the piston using the formula for the area of a circle (π x radius^2). Finally, multiply the area by the pressure to find the force.
A single layer of gold atoms forms a surface whose dimensions are 1000 angstroms X 1000 angstroms what is the surface area in square angstroms?
The surface area of a single layer of gold atoms with dimensions of 1000 angstroms x 1000 angstroms is 1,000,000 square angstroms. This can be calculated by multiplying the length by the width (1000 angstroms x 1000 angstroms = 1,000,000 square angstroms).
