Because of the cylinder's circular shape, its surface area includes a multiple of pi. Because pi is an irrational number, you can not express its exact value numerically.
The fact that you can't express it numerically does not however mean that you can't express it at all. For example, a cylinder with a radius of 1 centimeter and a height of 1 centimeter will have a surface area of exactly 4π centimeters.
The exact result depends on the exact ratio of length to diameter; but in principle, with a cylinder you need less surface area - and thus less material - for the same volume.
the measurement is not always exact and say you were to measure a football field and your measurement were to be exact it would be close to impossible
It is important because PRECISE means exact, and exact measurements are important because it tells you the actual measurement of an object, other than to tell you an estimate, not knowing the exact measurement of that object
Yes, the Pythagorean theorem gives the exact measurements always. It can be backed up by proofs and sin, cosine, etc.
An approximation error is the discrepancy between an exact value and the approximation to it. This occurs when the measurement of something is not precise.
You can find the exact surface area for all of those shapes.
What do you mean by "exact measurement"? Do you wish to determine the cylinder's height? Its diameter? Its surface area? Its volume?
The exact bore measurement is 101.6 mm.
41.3 is an exact measurement.
A graduated cylinder is a common container that measures liquid volume in exact milliliters. It typically has measurement markings engraved on the side to show precise volume increments.
The exact result depends on the exact ratio of length to diameter; but in principle, with a cylinder you need less surface area - and thus less material - for the same volume.
It uses smaller segments of measurement making it more accurate
If you measure properly, the amount of water does not change. Measurement with whatever graduated cylinder you choose will not alter the amount of liquid measured. Most people choose to measure once with a larger one, but if the amount of liquid falls between the measurement lines, you can measure the "leftover" with a smaller cylinder and find the exact answer.
The exact measurement in inches of an M3 screw size is 0.118 inches.
The exact measurement in millimeters of an M4 screw size is 4 millimeters.
Pyramid - square pyramid to be exact.
The exact Tagalog translation is "piramide".
