10cm
The diameter is twice the radius.
Radius of a circle is half its diameter, 1/2 of 5cm =2.5cm
2.5cm !
The circumference of a circle, if its diameter is 5cm, is about 15.71cm
The circumference of a circle with a radius 5cm is: 31.4 cm
The diameter is twice the radius.
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
2.5cm !
5cm since radius is one half the diameters.
5cm
The circumference of a circle, if its diameter is 5cm, is about 15.71cm
The circumference of a circle with a radius 5cm is: 31.4 cm
The circumference of a circle with a radius of 5cm is: 31.42 cm
diameter=10cm radius=5cm
if a radius is 5cm the diameter is 10cm rule- you double the radius
Do note that the perimeter/circumference of a circle can be found using this formula: πD or 2πr. Hence, with the information given that the circle has a radius of 5cm, the circumference of the circle is: Formula = πD Diameter = Radius x 2 = 5cm x 2 = 10cm π = 3.14 (depending on what the question states π to be) Circumference of the circle = 3.14 x 10cm = 314cm
