The radius of the circle is 5 cm, 3 dm, 2 m. Find its diameter.

In order to find the diameter, you need to know the formula for finding it. We know from the rule of mathematics that the diameter is twice the radius. Numerically, it will look like this:

d = 2r.

Now let’s apply this shape to our values. Numerically, it will look like this:

d = 5 * 2 = 10 cm.

d = 3 * 2 = 6 dm.

d = 2 * 2 = 4 m.

Thus, we get the answer to this problem in the given numbers and values.
