How do you find the volume of a marble?

Answer 1

To find the volume of a marble, you would use the formula for the volume of a sphere, which is V = (4/3)πr^3, where V is the volume and r is the radius of the marble. Measure the diameter of the marble and divide it by 2 to get the radius. Then, plug the radius into the formula to calculate the volume of the marble in cubic units.

Answer 2

There are several methods:

From geometry and the formula for the volume of a sphere:

Assuming the marble is a perfect sphere, the radius of the marble is one-half of the diameter, or width of the marble. Use the formula for volume,

V = (4/3) pi r3

where pi is approximately 3.1416 and can usually be found on a scientific calculator. R is the radius as mentioned before. The formula in text is "four-thirds times pi times the radius cubed." Make sure to do the cubing first.

From the displacement the marble causes in water or other liquid

you can measure the volume of a marble by filling up a glass beaker to whatever amount you'd like,then you would see how much the water went up.and that would be you answer

From the density of the marble

Weigh the marble and determine typical density of glass from available tables. As the density of the marble is found by the formula

Density=mass/volume,

divide the mass in grams by the density in gm/cm3 to determine the volume in cm3.
