This theorem requires a proof..
You can help $\mathsf{Pr} \infty \mathsf{fWiki}$ by crafting such a proof.
Theorem
The value of $\pi$ lies between $3 \frac {10} {71}$ and $3 \frac 1 7$:
- $3 \dfrac {10} {71} < \pi < 3 \dfrac 1 7$
Proof
You can help $\mathsf{Pr} \infty \mathsf{fWiki}$ by crafting such a proof.

If you would welcome a second opinion as to whether your work is correct, add a call to {{Proofread}} the page (see the proofread template for usage).
Historical Note
Archimedes demonstrated the limits to the value of $\pi$ in his Measurement of a Circle.
