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

If the diameter is 12 cm the radius is 6 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.

the diameter of a circle is double the radius so if the radius is 12 cm then the diameter is 24 cm

diameter = radius × 2 → radius = diameter ÷ 2 = 10 cm ÷ 2 = 5 cm
