A circle has a circumference of 31.4 cm. What is the radius of the circle?
["Why More People Are Exploring: A Circle Has a Circumference of 31.4 cm and What It Really Means", "Curious about math in everyday life? A relatively simple question—A circle has a circumference of 31.4 cm. What is the radius?—sparks unexpected interest amid rising curiosity about geometry, design, and real-world measurements. Rising attention reflects growing awareness of basic math’s role in everything from fashion and fitness to tech and architecture. As people seek clarity on familiar shapes, this precise calculation becomes a gateway to understanding proportions and precision in design.", "If you’ve paused here wondering, “How do you find the radius from the circumference?” you’re not alone. The answer lies in the elegant math behind circles, and it’s simpler than it might seem—especially when presented in a clear, moveable format optimized for mobile search.", "The foundation: The circumference of a circle relates directly to its radius through the formula \( C = 2\pi r \), where \( C \) is circumference and \( \pi \) (approximately 3.14) governs curvature. Rearranging gives \( r = C / (2\pi) \). Inputting \( C = 31.4 \) cm turns the calculation into: \n\( r = 31.4 / (2 \ imes 3.14) = 31.4 / 6.28 = 5 \) cm. \nSo, the radius is exactly 5 centimeters—a figure that resonates across practical applications from product design to physical fitness tracking.", "In the United States, this calculation pops"]
