Instrument Used To Measure The Diameter Of A Marble

R3 3 volume of sphere.

Instrument used to measure the diameter of a marble.

If you know the radius of a circle you multiply it by 2 to get the diameter. The measurement is shown in the figure 2. Write down the measurement. My idea is that with this system the largest size of the marble is measured.

We used this instrument in a physics lab to measure the diameter of a tennis ball marble etc. Measure the perimeter of the wheel using a tape measure. You use a triple beam scale to measure mass. Most templates measure to 16ths of an inch.

Then use the formula to find out the diameter d perimeter 3 14 you could certainly do it that way. Lay a marble template on the tissue and try the marble in the different holes until you find the one closest to the size of the marble. What is an instrument that measures mass. If you can t do that then somehow measure the diameter of the marble divide it by 2 to find the radius and plug it into this formula.

A balanced scale which compares the mass of one object with that of a known quantity. If you know the circumference of a circle you divide by pi to get the diameter you measure it. Now let us use this vernier calipers to measure the diameter d of a marble ball marble balls usually have d 1 2 in.
