The radius of a circle is the distance from the centre to the edge. The diameter is the distance right across the circle through the centre. So the diameter of a circle is always twice its radius. So if the radius of a circular CD is 6cm, the diameter is twice this - 12cm.

Draw a circle of 6 cm and find the radius?

If the diameter is what you are talking about that is 6 cm, you must divide that number by two to find the radius because the radius is half a diameter. The radius of a circle with a diameter of 6 cm. would be 3 cm.

What is the radius of a circle that is 12 cm in diameter?

6 cm. The radius is 1/2 of the diameter.

Radius is 3 cm what is diameter?

Since with circles the radius is half the diameter, the diameter would be 6 cm.

If the diameter of a circle is 12 cm long how long is the radius?

The radius would be 6 cm because the diameter is 2 times bigger than the radius.

What is the area of a circle with a diameter of 6 Cm?

The area of a circle can be calculated using the formula A = πr^2, where r is the radius of the circle. Since the diameter is twice the length of the radius, the radius of a circle with a diameter of 6 cm is 3 cm. Plugging this value into the formula, we get A = π(3)^2 = 9π cm^2. Therefore, the area of a circle with a diameter of 6 cm is 9π square centimeters.
