The radius of a circle equals the diameter divided by two. 30/2 is 15, so your answer is 15 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 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
15 cm
7.5Radius of circle: 15/2 = 7.5 cm
The radius of a circle equals the diameter divided by two. 30/2 is 15, so your answer is 15 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 radius (radii) of a circle is 1/2 of the diameter. The radius of a circle with a 6.2 cm diameter is 3.1 cm.
Diameter is twice the radius, so 15 cm.
The radius of a circle is half of its diameter
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
10 cm; the diameter of a circle is twice its radius.
A circle with a radius (d/2) of 15 cm has a circumference of 94.2 cm
