Answer:
The term "diameter" refers to a straight line segment that passes through the center of a circle or sphere, connecting two points on the circumference or surface. It is the longest distance that can be measured within the circle or sphere. The diameter is essentially double the length of the radius, which is the distance from the center to any point on the circumference or surface. In mathematical terms:
For a circle, the diameter
d is related to the radius
r by
=
2
d=2r.
For a sphere, the diameter
d is related to the radius
r by
=
2
d=2r.
The diameter is a fundamental measurement used in geometry and engineering to describe the size of circles, spheres, cylinders, and other round objects. It helps in calculating various properties such as circumference, area, volume, and more.
