A flying disc has an area of about \( 491 \mathrm{~cm}^{2} \). What is the diameter of the disc to the nearest tenth of a centimeter? 11.1 cm 25.0 cm 22.2 cm 12.5 cm

To find the diameter of the flying disc, we can use the formula for the area of a circle, \( A = \pi r^2 \), where \( r \) is the radius. Since we need the diameter, we’ll use \( d = 2r \). Given the area \( A = 491 \mathrm{~cm}^2 \): 1. Rearranging the formula gives \( r = \sqrt{\frac{A}{\pi}} \). 2. Plugging in the area, we get \( r = \sqrt{\frac{491}{\pi}} \approx 12.5 \) cm. 3. Thus, the diameter \( d = 2r \approx 25.0 \) cm. So, the correct answer is **25.0 cm.** The plight of the flying disc isn’t just about an afternoon throw—there’s a whole history behind it! Originating from the 19th century, it started with flying pie tins thrown for fun at picnics. Fast forward to the 1960s when the modern Frisbee was patented, and voila! It transformed into a craze, paving the way for disc sports we enjoy today, turning casual picnics into thrilling competitions. Want to ace your next disc-throwing party? Avoid common mistakes like using too much wrist flick or not enough spin, both of which can send your disc spiraling out of control. Focus on keeping a smooth, level throw and following through your motion for better distance and accuracy. Plus, a little practice can turn you into the neighborhood’s frisbee champion in no time!
