diametre of circle
4 times pi. That is about 12.57.
Diametre = 2*radius so diameter = 24.8 metres.
Diametre is, since diametre = 2*radius
2*radius=diametre radius=2.1 Area=pi*(radius)^2 Area=3.1428*2.1*2.1 Area=13.86
pi * diameter
2.35
It is 25cm
92mm
Times the diametre by pi
40*pi metres
If you had a circle and cut along the diametre you would get two half cirlces.
d = 11.46 inches
4 times pi. That is about 12.57.
A diametre =2 aligned rayons it is a line from aside to a circle to another by passing from the center of the circle.
The circumference of a circle = pi*diametre = 2pi*radius
that is the radius. the diametre is the line going right accross the middle of the circle
The diameter (not diametre) of a circle is a segment of a straight line going from the circumference (or perimeter), through the centre of the circle, to meet the circumference on the other side. A diameter of a sphere is defined analogously.
