The radius of the circle is approximately 20 feet.

Solución

We know the formula for the circumference of a circle is:   Circumference = 2πr Given that the circumference is 125.66 feet, we can set up the equation:   125.66 = 2πr To solve for the radius r, divide both sides of the equation by 2π:   r = 125.66 / (2π) Using π ≈ 3.1416:   r ≈ 125.66 / (2 × 3.1416)   r ≈ 125.66 / 6.2832   r ≈ 20 feet Therefore, the radius of the circle is approximately 20 feet.

To find the radius, we can use the formula for the circumference of a circle: C = 2πr, where C is the circumference and r is the radius. Rearranging the formula to solve for the radius gives us r = C / (2π). Plugging in the given circumference of 125.66 feet, we get r = 125.66 / (2 × 3.14), which equals 20 feet. So, the radius of the circle is 20 feet! Now, isn't it fascinating how circles are everywhere in our lives? From the wheels on your bike to the design of your favorite pizza, their perfect roundness brings both function and flair! And speaking of pizza, imagine sharing a cozy night in with friends, measuring out those perfectly circular slices. Cheers to geometry making our meals more enjoyable!
