Question

A circle has a circumference of 11,304 units. What is the diameter of circle?

Answer 1

Answer:

$D\approx 3600$

Step-by-step 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 $\pi$

$C=2\pi R \Rightarrow C=\pi D \Rightarrow D=\frac{C}{\pi} \Rightarrow D=\frac{11304}{\pi} \Rightarrow D\approx 3600$

Answer 2

Greetings!

Answer:

3598 (or 3600 to 2.s.f)

Step-by-step 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

Hope this helps!
