The circumference of a circle, if its diameter is 5cm, is about 15.71cm
The radius of a circle is half the diameter. So if the diameter is 5cm, the radius would be 2.5cm.
Radius of a circle is half its diameter, 1/2 of 5cm =2.5cm
10cm
5cm
2.5cm !
15.71 cm
The diameter is twice the radius.
360. There are 360 degrees in every triangle.
Radius is from the centre to edge so is 5cm.
5cm
The circumference of a circle with diameter D is πD where π = 3.14159 approx. So D = 5 gives a circumference of 15.7 cm
