Question

What is diameter?
Please answer​

Answer 1

Answer:

In geometry, a diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for the diameter of a spher

Explanation:

Formula:

Diameter given radius

d = 2r

d = diameter

d = diameterr = radius

The diameter is essentially composed up of two segments that are each a radius. Thus, the diameter formula is Diameter = 2 × the measurement of the radius. You can write this formula in shorthand as d=2r.

Answer 2

• Any straight line segment that goes through the circle's center and whose ends are on the circle is referred to as a circle's diameter.
• The circle's longest chord can alternatively be described as this.
• The diameter of a sphere can be defined using either concept.
• The length d of a diameter is also referred to as the diameter in current use.
• Because all diameters of a circle or sphere have the same length, which is twice the radius r, one speaks of the diameter rather than a diameter (which refers to the line segment itself) in this context.
