Question

The circumference of the Ferris wheel at the county fair is 78.5 feet. What is the diameter of the Ferris wheel, in feet? Use 3.14 for π .

Answer 1

To find the diameter of the Ferris wheel with a circumference of 78.5 feet, divide the circumference by π (3.14) to get approximately 25 feet.

Step-by-step explanation:

The circumference C of a circle relates to its diameter d through the formula C = πd. Since we are given the circumference of the Ferris wheel as 78.5 feet and asked to use 3.14 as the value for π (pi), we can solve for the diameter by rearranging the formula to d = C/π.

To calculate the diameter of the Ferris wheel:

1. Divide the circumference by π: d = 78.5 ft / 3.14.
2. Perform the division to find the diameter: d ≈ 25 ft.

So, the diameter of the Ferris wheel is approximately 25 feet.
