    The solution:

    Vertical side divided by 5:
    1 / 5 = 0.2
    That amount multiplied by 3 to get the diameter:
    0.2 x 3 = 0.6
    That amount divided by 2 to get the radius:
    0.6 / 2 = 0.3

    0.3cm → 3mm

    The ratio between the sizes of the vertical and horizontal sides is 2:3. The placement of the hi no maru is at the center. The diameter of the hi no maru is set as 3/5 of the size of the vertical side. Hi no maru: red circle meant to represent the sun.

    The day in which the design and standards of the Japanese national flag were determined by the Merchant Ship Regulations, in the 3rd year of the Meiji era (1870)

    Given a national flag of a vertical side of 1cm, calculate the radius of the hi no maru.
