To find the diameter of the circle given its circumference, we can use the formula for the circumference of a circle:

$C = \pi d$

Where:

• $C$ is the circumference,
• $d$ is the diameter,
• $\pi$ is approximately 3.1416.

Given that the circumference $C = 27$ cm, we can solve for $d$ as follows:

$d = \frac{C}{\pi} = \frac{27}{3.1416} \approx 8.6 \, \text{cm}$

Thus, the diameter of the circle is approximately 8.6 cm to 1 decimal place.

1. How do you calculate the radius if the diameter is known?
2. What is the formula to find the area of a circle using the diameter?
3. If the circumference were 30 cm, what would the diameter be?
4. How does the value of $\pi$ affect the diameter calculation?
5. Can the circumference of a circle be a negative value?

Tip: Always remember that the diameter is twice the radius, so you can also calculate it if the radius is given!
