Instrument Used To Measure The Diameter Of A Marble

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.

Instrument used to measure the diameter of a marble.

Measure the perimeter of the wheel using a tape measure. The measurement is shown in the figure 2. If you know the radius of a circle you multiply it by 2 to get the diameter. I have seen cards boards with different size holes in it to use for measuring the size of marbles.

What is an instrument that measures mass. R3 3 volume of sphere. My idea is that with this system the largest size of the marble is measured. 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.

If you know the circumference of a circle you divide by pi to get the diameter you measure it. 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. We used this instrument in a physics lab to measure the diameter of a tennis ball marble etc. A balanced scale which compares the mass of one object with that of a known quantity.
