A Ferris wheel has a radius of 30 feet and travels 3.6 feet every second. How long does it take for the Ferris wheel to complete one revolution?
circumference = 2 pi r = 188.5 feet
188.5 feet ( 1 second/ 3.6 feet) = 52.4 seconds
To find out how long it takes for the Ferris wheel to complete one revolution, we need to determine the circumference of the wheel.
The circumference of a circle can be calculated using the formula:
C = 2πr
Where C is the circumference and r is the radius.
Substituting the given radius, we have:
C = 2 × π × 30 ft
C ≈ 60 × π ft
C ≈ 188.5 ft (approx.)
Since the Ferris wheel travels 3.6 feet every second, we can divide the circumference by the speed to find the time taken to complete one revolution.
Time = Circumference / Speed
Time = 188.5 ft / 3.6 ft/s
Time ≈ 52.4 seconds (approx.)
Therefore, it takes approximately 52.4 seconds for the Ferris wheel to complete one revolution.
