Cylinders are measured using heights rather than lengths because height refers to the vertical dimension of the cylinder, which is crucial for determining its volume and capacity. The height, combined with the radius of the base, allows for the calculation of the cylinder's volume using the formula ( V = \pi r^2 h ). Length, on the other hand, could imply measurement in any direction, which would not provide a clear understanding of the cylinder's three-dimensional shape and size. Thus, height is a more relevant and standardized measurement for cylinders.

Bond lengths are measured by?
Bond lengths are measured using techniques such as X-ray crystallography, which allows scientists to determine the distances between atoms in a crystal structure. Other methods include spectroscopy, such as infrared or nuclear magnetic resonance (NMR) spectroscopy, which can provide insights into molecular geometry. Additionally, computational chemistry can predict bond lengths through quantum mechanical calculations. These measurements are crucial for understanding molecular structure and reactivity.
How are lengths of timber measured?
Lengths of timber are typically measured using either imperial or metric units, with common measurements being in feet and inches or meters and centimeters. Measurement is often done with a tape measure, ensuring accuracy by placing the end of the tape at one end of the timber and extending it to the other end. It's important to measure straight along the length of the timber, avoiding any curves or irregularities. Additionally, some timber may be sold in standardized lengths, which can simplify the measurement process.
How do you find angles in a triangle using only the lengths?
By using trigonometry
How can acceleration be measured?
Acceleration can be measured using an accelerometer.
How can we use a broken ruler to measure the perimeter of the shapes?
To measure the perimeter of shapes using a broken ruler, you can use the intact sections of the ruler to measure the lengths of each side of the shape. If the ruler has markings, take note of the measurements, and for any broken parts, estimate the lengths based on the remaining sections. Alternatively, you can place the ruler alongside the shape and use it as a reference for proportional measurements. Finally, sum the measured lengths to find the total perimeter.
When using the metric system length can be measured by what?
All lengths are measured in metres.
How mount Everest is measured in heights in picture form or diagram from bottom to the top?
We cannot (yet) display diagrams or pictures, however mountains are usually measured using trigonometry. Which is a system in mathematics used to calculate the lengths and angles in a triangle without physically measuring them.
How can matter be measured?
Matter can be measured by its mass, which is the amount of material in an object. This can be measured using a scale or balance. Another way to measure matter is by its volume, which is the amount of space it occupies. This can be measured using tools like rulers, graduated cylinders, or beakers.
What can be measured using millilitres?
Small volumes of liquid, such as raindrops, tears, small medicinal doses.
How is height measured in the metric system normally?
Height is typically measured in the metric system using meters or centimeters. Tall heights are often expressed in meters, while shorter heights may be given in centimeters. For example, a person who is 1.75 meters tall could also be expressed as 175 centimeters.
What is used to measure fluids?
You can measure fluids in beakers, graduated cylinders or liquid measuring glasses. It depends on what you're measuring and why.
Methods used to determine the height of mount Everest?
In 1856, the Great Trigonometrical Survey of India measured Mount Everest using theodolites each weighing 500 kg (1,100 lb) and requiring 12 men to carry, to measure heights as accurately as possible. Today it is measured using satellite and GPS.
Why is using the standard unit of a foot more practical than using your own foot as a unit of measure?
Peoples feet come in various sizes (just look in a shoe shop) and thus if we each measured foot lengths using our own feet we would all come up with different absolute lengths and nothing we wanted to do co-operatively would ever fit together.
Write a real-world problem using ratios that could be represented on the coordinate plane?
One example is the lengths of all the items on your desk, measured in centimetres (x-axis) and inches (y-axis).
How voltage measured?
It is measured using a Voltmeter

What is mass volume length and how do you measure them?
Mass, volume, and length are fundamental physical quantities used to describe objects. Mass measures the amount of matter in an object, typically in grams or kilograms, and is measured using a balance scale. Volume refers to the space an object occupies, measured in liters or cubic meters, and can be determined using graduated cylinders or water displacement for irregular shapes. Length is the distance between two points, measured in meters or centimeters, commonly using rulers or tape measures.
