the diameter of a circle is double the radius so if the radius is 12 cm then the diameter is 24 cm
Radius of a circle is half of its diameter and so 12/2 = 6 cm
The diameter of a circle is twice its radius. Thus the radius of a circle is half its diameter. → a circle with a diameter of 15 cm has a radius of 15/2 cm = 7.5 cm
12 cm.
The diameter of a circle is double the radius. So a circle with a radius of 7 cm has a diameter of 14 cm.
