Question

You have a circle with a diameter of 24 divided into 16 sections what is the size of each section

Answer 1

The circle with diameter of 24 means that 2$\pi$r = 24. 

Solving for r, we get $\pi$r=24. 

Dividing both sides by $\pi$, we get r=24/$\pi$.

The area of the full circle is $\pi$ times 24 squared over $\pi ^{2}$. The $\pi$ being multiplied cancels out, meaning that 24 squared over $\pi$ is the area of the full circle. 24 squared is 576, and dividing by 16 we get $\frac{36}{\pi}$ as the answer.
