läbimõõdus

Läbimõõdus is an Estonian term that translates to "diameter" in English. It refers to a straight line segment passing through the center of a circle or sphere, with its endpoints lying on the boundary of the shape. The length of this line segment is also known as the diameter. In mathematics, the diameter is a fundamental property of circles and spheres, and it is directly related to other important measurements such as the radius (which is half the diameter) and the circumference or surface area. The diameter is often denoted by the symbol 'd'. Understanding the diameter is crucial in various geometric calculations and real-world applications, including engineering, physics, and everyday measurements. For instance, when measuring the size of pipes, circular objects, or even the width of a circular opening, the diameter is the standard measurement used. Its value can be found by multiplying the radius by two or by dividing the circumference by pi (π).
