Diameter of a circle: A line that is drawn from one point on a circle to a point exactly opposite, traveling through the center point. Radius: a line from the center point of a circle traveling to a point in a circle. The diameter is measured all the way through a circle, and a radius is from the center point out, so the radius of a 1cm diameter circle is .5 cm.

Don't over-complicate it. It is .5 cm. Radius is always half the diameter or the distance from the center to the edge of a circle. The diameter is the distance all the way across it.

2.4649 cm. Because you take pi (3.14) times the radius (which is half of diameter, .5 cm) and then square it (times it by itself).
Oh sorry, that was the circumfrance... but yes, the radius is always half the diameter, making it .5 cm in this case. Radius=halfway across circle. (You can take the point in the exact middle and measure to any point on the edge of the circle.

The radius is half the diameter = 1cm ÷ 2 = 0.5 cm = 5mm.
The reason is that, that is what it is.

the radius of the circle will be 0.5 cm because the radius if half the diameter.

.5 cm
Radius is 1/2 diameter

.5cm / 5mm
radius = 1/2 diameter

well the radius is just half of the diameter... so .5cm, or 5mm would be an acceptable answer
2007-07-17 13:05:26 · answer #9 · answered by Anonymous · 1⤊ 0⤋
radius is 0.5 cm because radius is defined as half the diameter.

The radius of any circle is half of its rasdius...........
In your case that would be 1/2 or 5mm...................
