If a circle has a circumference of about 12.56 cm, what would we do to determine the radius? Use 3.14 as “pi”.

Respuesta :

We are told that the circle’s circumference is 12.56 cm. So, to find it’s diameter, we have to divide 12.56 by 3.1416.

The answer is approximately 3.9979 which is VERY close to 4, so we can say that the diameter of the circle is approximately 4 cm.
