Answer 1

The circumference of the yellow circle is
`9\pi` or
`28.27cm^2` approximately, the circumference of the blue circle is
`6\pi` or
`18.85m^2` approximately, the circumference of the green circle is
`80\pi` or
`251.33mm^2` approximately, the circumference of the red circle is
`5\pi` or
`15.71cm^2` approximately, and the circumference of the pink circle is
`7\pi` or
`21.99cm^2` approximately.

Explanation:

To find the circumference of a circle, you need to multiply the diameter of the circle and multiply it by
`\pi`. In this case, the circumferences of the yellow circle are
`9\pi` or approximately
`28.27cm^2`, the circumference of the blue circle is
`6\pi` or approximately
`18.85m^2`, the circumference of the green circle is
`80\pi` or approximately
`251.33mm^2`, the circumference of the red circle is
`5\pi` or approximately
`15.71cm^2`, and the circumference of the pink circle is
`7\pi` or approximately
`21.99cm^2`.
