that is the radius. the diametre is the line going right accross the middle of the circle
circumference = 2pi50 = 314.159 cm to 3 decimal places

half of a diametre is radius. hence multiply the diameter by 0.5 then use the formular of cicumference, which is 2*pie*r
92mm
Measure the diametre of the circle and divide by two to give the radius.
diametre of circle
Diametre = 2*radius so diameter = 24.8 metres.
The circumference of a circle = pi*diametre = 2pi*radius
Diametre is, since diametre = 2*radius
No. An arc is part of the circumference - the rounded bit.

2*radius=diametre radius=2.1 Area=pi*(radius)^2 Area=3.1428*2.1*2.1 Area=13.86
a circle with an area of 50cm has an area of 50cm... why did you even ask this question
To calculate the radius is very easy, the formula is d/2 where d is diametre. therefore according to d/2 = 9cm/2 which is equals to 4.5 cm Result : the radius of a circle with a diameter of 9 cm is 4.5 cm.
