The diameter of a circle is twice the length of its radius. Therefore, if the radius is 25 cm, the diameter would be 2 x 25 cm = 50 cm. The diameter is a straight line passing through the center of the circle and connecting two points on the circle's circumference.
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
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 radius of a circle is half of its diameter
the diameter of a circle is double the radius so if the radius is 12 cm then the diameter is 24 cm
