Answer:

Diameter : 7.8cm ; circumference ≈ 24.5 cm

Explanation:

The diameter of a circle is equal to twice the radius.

\The radius is given by 3.9cm

Thus, diameter = 3.9 x 2 = 7.8cm.

Circumference = 2 π r or πd

we know that d = 7.8 cm

Therefore, circumference =

3.14 x 7.8 = 24.492

≈ 24.5 cm. Hope this helps! :]
