To find the diameter of a circle given its circumference, you can use the formula:
\[ C = \pi \cdot d \]
where \( C \) is the circumference and \( d \) is the diameter.
Given that the circumference (C) is 24 cm and using \( \pi \approx 3.14 \), we can rearrange the formula to solve for the diameter (d):
\[ d = \frac{C}{\pi} \]
Now substitute the values:
\[ d = \frac{24 \text{ cm}}{3.14} \]
Calculating that gives:
\[ d \approx 7.64 \text{ cm} \]
Rounding to the nearest tenth:
\[ d \approx 7.6 \text{ cm} \]
So, the diameter is about 7.6 cm.
