It is known that the radius is the distance from the center of the circle to any point on the circle. Then the diameter of the circle is D = 2 * R.
The radius of the first circle is R = 5 mm. Then the diameter of the circle is D = 2 * 5 = 10 mm.
The radius of the second circle is R = 16 cm. Then the diameter of the circle is D = 2 * 16 = 32 cm.
The radius of the third circle R = 9 dm. Then the diameter of the circle D = 2 * 9 = 18 dm.
The radius of the fourth circle is R = 10 m. Then the diameter of the circle is D = 2 * 10 = 20 m.
