[tex]C=94.2\text{ cm}[/tex]
Explanation
Step 1
the circumference of a circle is given by:
[tex]C=2\cdot\pi\cdot\text{radius}[/tex]
so, by the image
Let
radius=15 cm
pi=3.14
Step 2
replace,
[tex]\begin{gathered} C=2\cdot\pi\cdot\text{radius} \\ C=2\cdot3.14\cdot15 \\ C=94.2\text{ cm} \end{gathered}[/tex]
