Answer:
31.4 cm
Step-by-step explanation:
Circumference of the circle = 2×π×r
Circumference of the circle= 2×3.14×5
Circumference of the circle = 10×3.14
Circumference of the circle= 31.4cm
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]
