the radius is one-half the diameter
radius = diameter/2
diameter = 2 x radius
Diametre is, since diametre = 2*radius
It is 25cm
92mm
Measure the diametre of the circle and divide by two to give the radius.
Diametre = 2*radius so diameter = 24.8 metres.
The circumference of a circle = pi*diametre = 2pi*radius
No. An arc is part of the circumference - the rounded bit.
Circumference of a circle = 2*pi*radius or diameter*pi
2*radius=diametre radius=2.1 Area=pi*(radius)^2 Area=3.1428*2.1*2.1 Area=13.86
Area = (pi) x (Radius)2 (Radius)2 = Area/pi Radius = sqrt(Area/pi) Diameter = 2 x radius = 2 x sqrt(Area/pi)
that is the radius. the diametre is the line going right accross the middle of the circle
