The area of a circle is represented by the equation:

$A=\pi r^{2}$

We know that the diameter is two times the radius: $d=2r$

So if we know that the diameter of the circle is 24m, we can divide this by two in order to get the radius:

$24m=2r$ --> $r=12m$

So then we can plug this radius in to the equation for the area of a circle:

$A=\pi (12)^{2}$

$A=144\pi$

We are told to use 3.14 as pi, and not pi itself, so let's plug in 3.14 for pi:

$A=3.14(144)$

$A=452.16m^{2}$

Now we know that the area of this circle is 452.16 square meters.
