the diameter
The longest distance across a circle is its diameter and the shortest distance is a minor chord
It is simply called the distance between the two points - simple as that. How that distance is measured will depend on the nature of the surface on which the two points are located as well as on the metric for measuring distance that is defined on that space.The common metric in Euclidean space is the Pythagorean distance while on the surface of a sphere (like the Earth, for example), distances are measured along the great arc.
The distance from the equator measured in degrees is called latitude.
Distance north or south measured in degrees is called latitude.
'Distance' can't be measured in degrees.The angle from the equator to the place of interestis the latitude of the place.
The distance half way across a circle is the circle's radius.radias
Systolic Pressure
I think you mean the distance from the Earth to the Sun. This distance is measured in Astronomical Units (AU)
Originally, the distance was measured by a system called parallax measurement. Today, it is measured by laser beam, and is accurate to within inches.
diameter
The force measured over an area is called pressure. It is calculated by dividing the force applied by the area over which it is distributed. Pressure is commonly measured in units such as Pascals or pounds per square inch (psi).
It's called the diameter.
Velocity.
Electrical pressure, also known as voltage, is measured using a tool called a multimeter. The multimeter is typically set to measure voltage, and the probes are connected to the circuit or component where the voltage is to be measured. The reading displayed on the multimeter indicates the electrical pressure in volts.
