Hello !

Answer:


\large\boxed{\sf Option\ 3 : 66cm}

Explanation:

The circumference of a circle is given by
\sf C=2*\pi* r, where r is the radius.

Given :

  • d = 21 cm
  • r = d/2 = 10.5 cm
  • π =3.14

Let's replace r with its value in the previous formula :


\sf C=2* 3.14* 10.5


\sf C=65.94


\boxed{\sf C\approx 66cm}

Have a nice day
