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
The circumference of a circle with a radius 5cm is: 31.4 cm
The radius of a circle is half the diameter. So if the diameter is 5cm, the radius would be 2.5cm.
The circumference of a circle with a radius of 5cm is: 31.42 cm
Radius of a circle is half its diameter, 1/2 of 5cm =2.5cm
If the diameter of a circle is 69mm then the circumference is: 216.8mm (diameter x pi = circumference).
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
The circumference of a circle 5cm in radius is about 31.42cm
Exactly the same because the perimeter of a circle is its circumference
