A caliper and a micrometer are commonly used instruments to measure the diameter of a material. A caliper is suitable for larger diameters, while a micrometer provides more precise measurements for smaller diameters. Both instruments come in different types and configurations to suit various measurement needs.
That would depend on what fruit it is exactly, apple, orange, what? Plus even individual fruits are not all the same size, such as two apples, for instance.
Mechanical calipers are typically used to measure the distance between two opposing sides of an object, such as the outer diameter of a circular object or the thickness of a material. They are suitable for measuring various substances like metal, plastic, wood, paper, and fabric.
Examples are: promethium is used in instruments to measure thickness of coatings, cerium is used in TV screens and fluorescent lamps.
Unit for time is a second.There are various instruments to measure temperature: a thermometer, a thermocouple are two.
A caliper is a common tool used to measure the diameter of a metal rod. It consists of two hinged legs with a scale and a mechanism to precisely adjust the distance between the tips. By placing the rod between the tips and closing the caliper, the diameter can be accurately read off the scale. Calipers come in various types such as digital, dial, and vernier, each offering different levels of precision.

Two instruments that could be used to measure curved lines are a flexible ruler and a caliper. A flexible ruler, also known as a contour gauge, can be molded to the shape of the curved line to measure its length accurately. A caliper, specifically a vernier caliper, can be used to measure the diameter or thickness of a curved object by gently gripping and measuring across the curve.
24 meters diameter is simply two times the radius.
Measure the distance between the two end points!
Measure the outside diameter and subtract tooth height times two.
The modern family of brass instruments can be broken into valved brass instruments (trumpet, horn, euphonium, tuba) and slide brass instruments (trombone). Brass instruments could also be broken up into Cylindrical bore (constant diameter tubing like the trumpet and trombone) and Conical bore (increasing diameter tubing like the horn, euphonium, and tuba).
Instruments that measure rheological properties are called Rheometers. They impose specific deformation to the fluid and monitor the results. The two operating modes include steady and oscillator flow.
A manometer instrument is used to check the alignment of two shafts.

Radius is calculated by dividing diameter by two. Measure the distance across the circle then divide it in half for example: You measure the distance across the circle (the diameter) = 6, then 6 divided in half, the radius is 3.
