The distance from the edge of a circular lake to its centre is 149 m . Bradley walks all the way around the edge of the lake. How far does Bradley walk? Give your answer to 1 d.p.

To find out how far Bradley walks around the edge of the circular lake, you can use the formula for the circumference of a circle, which is \( C = 2\pi r \), where \( r \) is the radius. Given that the distance from the edge of the lake to its center is 149 m, we can plug that value into the formula: \[ C = 2 \pi \times 149 \approx 937.0 \, \text{m} \] So, Bradley walks approximately 937.0 m when he circles the lake. Did you know that the word "circumference" comes from Latin? It's derived from "circumferentia," which means "carrying around." Ancient civilizations like the Greeks and Romans were fascinated by circles and developed various methods for calculating areas and circumferences. The fascination with circular shapes continues today, influencing everything from architecture to art! In real-world applications, understanding the concept of circumference can help you plan more than just leisurely walks around lakes! For example, if you're creating a circular garden, knowing how much fencing you need can save both time and money. Just remember, when you get to the store, always double-check the measurements—those long rolls can sneak up on you if you underestimate!
