Answer:

3598 (or 3600 to 2.s.f)

Explanation:

You need to recall that the circumference is π * d

So if we have the circumference, we can divide by π to get d:

11,304 ÷ π = 3598 or 3600 to 2.s.f

Answer:

$D\approx 3600$

Explanation:

Circumference is given by this formula below. What gives us the radius.

$C=2\pi R \Rightarrow 11304=6.28R \Rightarrow R=1800$

The diameter of the circle is calculated by dividing the Circumference, 11304 in this case by
$\pi$

$C=2\pi R \Rightarrow C=\pi D \Rightarrow D=(C)/(\pi) \Rightarrow D=(11304)/(\pi) \Rightarrow D\approx 3600$
