Question

what is diameters?

explaion me detail please​

Answer 1

1 : a straight line that runs from one side of a figure and passes through the center Measure the diameter of the circle. 2 : the distance through the center of an object from one side to the other : thickness the diameter of a tree trunk. diameter.

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 sphere.

Calculation

How To Calculate Diameter?

Diameter = Circumference ÷ π (when the circumference is given)

Diameter = 2 × Radius (when the radius is given)

Diameter = 2√[Area/π] (when the area is given)

Area of a circle can be calculated by using the formulas: Area = π × r2, where 'r' is the radius. Area = (π/4) × d2, where 'd' is the diameter. Area = C2/4π, where 'C' is the circumference.

Formula

Diameter given radius



=diameter=radius
