Final answer:
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:
- Divide the circumference by π: d = 78.5 ft / 3.14.
- Perform the division to find the diameter: d ≈ 25 ft.
So, the diameter of the Ferris wheel is approximately 25 feet.
