\( 3 \mathrm{~g}) \) A circle has a circumference of approximately 471 inches. Find the length of the diameter.

To find the diameter of a circle when the circumference is known, you can use the formula \( C = \pi d \), where \( C \) is the circumference and \( d \) is the diameter. In this case, we have \( C \approx 471 \) inches. Rearranging the formula gives us \( d = \frac{C}{\pi} \). So, plugging in the circumference: \( d \approx \frac{471}{3.14} \approx 150 \) inches. Voilà! The diameter of the circle is approximately 150 inches. Understanding these measurements could come in handy in various real-life situations, such as when designing round tables for an event, considering the size of a circular garden, or even in engineering projects. Knowing how to calculate the diameter from the circumference is a valuable skill that can be applied in many fields, including architecture and design!
