Question 3 \( \begin{array}{l}\text { Find the circumference of a circle with a diameter of } 50 \text { centimeters. Round your } \\ \text { answer to the nearest centimeter. } \\ \text { - } 16 \text { centimeters } \\ \text { o } 314 \text { centimeters } \\ \text { o } 157 \text { centimeters } \\ 079 \text { centimeters }\end{array} \)

To find the circumference of a circle, you can use the formula \( C = \pi \times d \), where \( d \) is the diameter. In this case, with a diameter of 50 centimeters, the circumference is \( C = \pi \times 50 \approx 157 \) centimeters when rounded to the nearest centimeter. The options provided include 16 centimeters, 314 centimeters, 157 centimeters, and 79 centimeters. The correct answer is 157 centimeters! In ancient civilizations, such as the Egyptians and Babylonians, the understanding of circles and their measurements was quite advanced. They had developed methods to approximate \( \pi \) long before calculators, using geometric shapes to help. This foundational math has evolved but remains essential to many fields today, including architecture and engineering!
