Since it's a "cylinder", then the volume is :
PI*R*R*H = Pi * 9.53 * 9.53 *1.55 = 442 mm^3
Hmm, didn't see the answer had to be in m^3, since there are 1 BILLION mm^3 in a m^3, the answer becomes:
4.42 x 10^-7 m^3 (0.000000442)

Volume = area x height
Area of a circle = pi x radius^2
Therefore, by replacing area in the first equation with the definition in the second equation the volume of your penny is pi x radius x radius x height
3.14 x 9.53mm x 9.53mm x 1.55mm = 422mm^3
Since 1000mm = 1m, you must divide your answer by 1/1000 three times to convert your answer into cubic meters (m^3). All this means is you need to move the decimal 3 places to the left for each division, for a total of 9 places to the left
0.000000422m^3 or 4.22x10^7 m^3 if you know how to convert to scientific notation

pi r^2 h
= pi 9.53^2(1.55)
= 442 mm^3
= 4.42x10^(-7) m^3
-------
Reason:
1m = 10^3 mm
1m^3 = 10^9 mm^3

volume of cylinder is area of circle times height. area is pi r sqrd approx 285.31. that times height is approx 442.24 mm cubed. there are 1 billion cubic millimeters in a cubic meter. so i guess 4.42 times 10 to the -7 cubic meters.

V = 2PIRH
= 9.53 * 9.53 * PI * 1.55
= 442 mm^3

Unfortunatly it is not a cylinder so you cannot use those measurements to find the volume of a penny. See the design on a penny? That design is cuased by indentations in the penny. And it is harder to find on the web that you might think.

likely about as "malleable" as a penny only watch it commerce, and also you need to have the ability to tell. yet many times, it truly is not a "procuring and promoting" inventory. it truly is like procuring and promoting after hours, and also you should apply particular precautions, like minimize orders. you do not ought to purchase all of it right away, do you? should be one helluva tale inventory in case you're keen to settle for the better possibility of a penny inventory to start with and shortage of liquidity. i'd difficulty extra about what's going to ensue once you opt for to get out.
