What do you want to measure about the marble? Its diameter, radius, circumference, volume, mass, density...?
The circumference of a regular-size marble, which typically has a diameter of about 1.5 centimeters (or 0.6 inches), can be calculated using the formula (C = \pi d), where (d) is the diameter. This results in a circumference of approximately 4.71 centimeters (or about 1.85 inches).
I would use a micrometer. A caliper would do as well.
A diameter of 3.5 cm is equivalent to approximately 1.38 inches. This size is similar to the diameter of a standard bottle cap or a small coin, making it relatively compact. To visualize it, it would be about the width of a large marble.

That depends what you want to measure: its diameter, its mass, its weight, its color, etc.

yes. the one-inch diameter marble could go faster than the other because it is heavier.

To find the volume of a steel marble, you can use the formula for the volume of a sphere, which is V = (4/3)πr^3, where r is the radius of the marble. Measure the diameter of the marble using a caliper, then divide it by 2 to get the radius. Plug the radius into the formula and calculate the volume using the value of π. This will give you the volume of the steel marble in cubic units.
