This is a science experiment and I need to know what the radius of a normal marble is.

Don't have a marble myself to measure the diameter

1. Measure the diameter.
2. Use the formula your math teacher taught you.

Just guess if this not the point of the experiment (it is a number or figure used to produce the desired outcome).
Other wise, find a test tube or a . . . something that you can easily determine the volume in cm cubed. fill with water, measure, place marble in, measure again. this will give you volume of marble in cm cubed. Work back to find circumference, diameter ect.
NOTE: Don't use liters or a volumetric measurement, diameter is length and that is what you need to stick to.

Measure the diameter and divide by 2 to get the radius.

Hi. Half the diameter. Measure this with a scale or ruler. About .250 inch.
