To calculate the diameter (d) of the circle, we can use the formula:

$d = \frac{C}{\pi}$

where:

• $C = 37 \, \text{cm}$ (the circumference of the circle),
• $\pi \approx 3.14$.

Now, let's calculate the diameter:

$d = \frac{37}{3.14}$

I'll compute this value.The diameter of the circle is approximately $11.8 \, \text{cm}$, rounded to the nearest tenth.

3. How can you use the diameter to find the area of a circle?
4. How does using a more accurate value for $\pi$ change the result?
5. How do you derive the formula for circumference?

Tip: Always remember that $\pi$ is an irrational number, so its value is infinite. Using 3.14 is a common approximation for basic calculations.
