Answer:

[tex]\large\boxed{C\approx31.4\ cm}[/tex]

Step-by-step explanation:

The formula of a circumference of a circle:

[tex]C=d\pi=2\pi r[/tex]

d - diameter

r - radius

We have the diameter d = 10cm. Substitute:

[tex]C=10\pi\ cm[/tex]

[tex]\pi\approx3.14[/tex]

Therefore

[tex]C\approx10(3.14)=31.4\ cm[/tex]
