Instrument Used To Measure The Diameter Of A Marble

You use a triple beam scale to measure mass.

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. If you know the circumference of a circle you divide by pi to get the diameter you measure it. Most templates measure to 16ths of an inch. 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.

Now let us use this vernier calipers to measure the diameter d of a marble ball marble balls usually have d 1 2 in. R3 3 volume of sphere. 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.

I have seen cards boards with different size holes in it to use for measuring the size of marbles. Measure the perimeter of the wheel using a tape measure. Write down the measurement. 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.

Then use the formula to find out the diameter d perimeter 3 14 you could certainly do it that way. As a marble is a sphere and a sphere is an endless number of circles it is impossible to squeeze a circle with a diameter of 2 1 2 inch through a 2 7 16 inch hole. A balanced scale which compares the mass of one object with that of a known quantity.
