Answer 1

`C=94.2\text{ cm}`

Step-by-step explanation

Step 1

the circumference of a circle is given by:

`C=2\cdot\pi\cdot\text{radius}`

so, by the image

Let

radius=15 cm

pi=3.14

Step 2

replace,

`\begin{gathered} C=2\cdot\pi\cdot\text{radius} \\ C=2\cdot3.14\cdot15 \\ C=94.2\text{ cm} \end{gathered}`
