If the volume of a ping pong ball is 2.045 in3, And the conversion of 2.045in3 to cm3 is equal to 33.5 cm3.So the volume of a ping pong ball in cm3 (Not cm... that's impossible...) is 33.5cm3!
To a first approximation, a tennis ball is a sphere. The volume of a sphere is V = 4/3 π r3, where r is the radius of the sphere. So measure the diameter of the tennis ball, divide by 2 to get the radius, and then apply the formula above. You could also measure the volume of a tennis ball by measuring the volume of water that it displaces.
you can do a simple easy experiment to find the volume of a ping ball (water displacment). Place the ping pong ball in an amount of water with a known volume in a SI unit of volume (mL, liters). Notice the water has risen. Subtract the vslue of the original water from the new value of the water. This is the ping pong's volume.
Volume = 4/3*pi*radius3 measured in cubic cm
Volume = 4/3*pi*2.53 = 65.449 cubic inches to 3 d.p.
to find the density of a base ball you have to divide the mass by the volume (m/v)
All that has changed is the shape.
Think of it this way if you have a golf ball and a wiffle ball they are the same size but they don't weight the same. The golf ball weighs more because it has a greater density In a more mathematical sense, density = mass / volume. If both minerals had the same mass, the more dense one must have a smaller volume.
The ball's volume is 0.25 L
Weight and density are two separate characteristics. Density is the mass of material in a volume of material (1 g/cm3) Weight is the force with which a mass is pulled onto the surface of another body. On Earth (for all normal considerations) 1 g (mass) is pulled towards the Earth with a force of 1 g (weight) A given volume of material will weigh more if the density of the material it is composed of is higher. That is, 1m3 of aluminum will weigh less than 1 m3 of steel.
Unless you can calculate or measure the volume, you cannot. And even if you could you would get the average density - of the material of the ball and the air inside.
Used the equation Density=Mass/Volume to solve this one.
There are several methods that can be used to calculate the density of a metal ball. The density of a metal ball can be derived from the fact that the volume is: 4*(pi)*r^3/3 and the denisty is mass/volume. If the mass and moment of inertia are known but the dimensions of the metal ball are not, then you can use the fact that the moment of inertia of the ball is 2m*r^2/5 and solve for m to get r=(5I/2)^.5 and plug in the value for r into the volume equation then calculate the density of the ball by dividing the mass by the calculated volume.
the yellow ball. density is mass / volume. 100/300= .33333 50/15=3.33333 3.33333>.33333
It's not correct to talk about "density" of a soccer ball. It's better you say "average density" of a soccer ball. It's clear that any soccer ball consists of different materials such as leather/plastic, rubber, and air. It order to find the average density you have to find the mass of a soccer ball and divide it by it's volume (in the first approximation you neglect the thickness of the shell (leather and rubber coats)).
Density = mass/volume let us say the mass of the steel ball and the ship are same. but the steel ball is fully enclosed, a tight spherical volume, where as the ship is a hollow, occupies more volume (multiple times) as that of the spherical ball. Considering the first equation, u know well the density of steel ball is much higher than the steel ship.
