A circle has a radius of $92.8\text{cm}$. What is the circumference of the circle? (Use $\pi =3.14$)

The formula for the circumference of a circle is given by:
$$\text{Circumference}=2\pi r$$

Given:

* Radius ($r$) = $92.8\text{cm}$
* $\pi =3.14$

Substitute the values into the formula:

$$\text{Circumference}=2\times 3.14\times 92.8$$

$$\text{Circumference}=6.28\times 92.8=582.784\text{cm}$$

Rounding to two decimal places gives $582.78\text{cm}$.
