Answer:

diameter = 3.31 mm (3 sf)

Step-by-step explanation:

  • Diameter of a circle (d) = 2r  (where r is the radius)
  • Circumference of a circle = 2[tex]\pi[/tex]r  (where r is the radius)
    ⇒ circumference = [tex]\pi[/tex]d

Given:

  • circumference = 10.4 mm

⇒ [tex]\pi[/tex]d = 10.4

⇒ d = 10.4 ÷ [tex]\pi[/tex] = 3.31 mm (3 sf)
