How much will a ball of a given diameter in a certain material weigh? The answer is calculated by multiplying the volume of the ball by the density of the material. Weight = Volume ⋅ Density For example, calculate the weight of a two inch diameter lead ball: Volume = 4 ⋅ π ⋅ R 3 3 π, a universal constant = 3.1416 4 ⋅ π = 12.566 R = Radius R =
So you must divide the mass of the ball by its volume. To do this, you must work out the volume of the ball and the mass. Typically the volume of a ball (sphere) is given by the formula Volume = 4/3 * pi ( roughly 3.141592654) * radius^3 You can simply weigh the mass. Once you have these, divide the mass by the found volume. 1.2K views View upvotes

One can from there estimate how many such spheres will fit. Your cylinder has volume V_c=pi*D^3. Your spheres are each V_s= 4/3*pi*d^3. Roughly 1/4 of the space is empty from the optimal packing ...
Answer (1 of 6): Well generally, density is found by dividing the mass of the object by its volume. The mass can be easily found by weighing, and since a ball is a sphere all you'd need is the radius of the ball (or diameter). Density = mass/volume Volume …

You drop a steel ball bearing, with a radius of 2.80 mm, into a beaker of honey. Note that honey has a viscosity of 4.00 Pa/s and a density of {eq}rm 1360 …
In this equation, V = volume and r = the radius of your ball or sphere. Firstly you'll need to find out the radius of your sphere. Next, cube your radius and multiply your cubed radius by 4/3. Now your equation should read V = .
Find the radius of the ball by first measuring the diameter (distance of a straight line through the ball at the widest part). Divide the diameter by 2; this gives the radius of your ball. Calculate the volume of the ball by plugging the radius into the equation for the volume of a sphere. Suppose the ball bearing has a radius of 0.01 meter (m).

A 7.0 kg steel ball of radius 4.0 cm rolls without slipping from rest down a hill of height 3.0 m. The ball continues to roll without slipping on a horizontal surface for a certain distance before striking a spring whose spring constant, k, is 72 N/m.The spring is originally unstretched.
Ball Bearing - A ball bearing uses loose balls to maintain separation between the two races. Roller Bearing - The same as a ball bearing but instead of balls, a roller is used to maintain the separation, Needle Bearing - a small bearing which uses small rollers to reduce the friction between the races.

The radius is the distance from the center to any point on the circle. Multiply the radius by two to produce a measurement for the diameter. Step 4 Measure the circumference (the length around the circle) of a circle that does not lend itself to measuring the diameter outright--something such as a pipe or a rod for which you cannot access the ...
8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball …
So we're gonna use sine theta. We're gonna say that the sine of theta, which is thirty, equals the opposite side, and that's r, divided by the total length of the string, L. And, so if I solve this for the radius, I get the radius of the circle that this ball is traveling in would be L times sine of thirty, where L would be this two meters.
We know the ball surface area formula now. As an example, the surface area of a ball with a radius of 10 cm can be found below: A = 4πr 2. A = 4π * 10 2 = 1256.64 cm 2. Now you know how to find the surface area of a ball. If you need a handy calculation tool to find the surface area of a ball, try out our ball surface area calculator.
