Respuesta :

Given: first circle is 11 km.

Find: circumference of each circle .

Explanation: if radius of circle is11 km.

the circumference of the circle is

[tex]\begin{gathered} =2\pi r \\ =2\pi(11) \\ =22\pi km \end{gathered}[/tex]

and the second one is 2 yd.

the circumference of the circle is

[tex]\begin{gathered} =2\pi r \\ =2\pi(2) \\ =4yd \end{gathered}[/tex]

Final answer: the circumference of the first circle is 22pi and the second one is 4pi yd
