the ferris wheel at a carnival has a diameter of 18 m and descends to 2m above the ground at its lowest point. Assume that a rider enters a car at this point and rides the wheel for two revolutions
Ok. Assumption made. Now what?
To calculate the total distance traveled by the rider during two revolutions on the Ferris wheel, we need to find the circumference of the Ferris wheel and multiply it by two.
First, let's calculate the circumference of the Ferris wheel using its diameter. The formula for the circumference of a circle is C = π * d, where C represents the circumference and d represents the diameter.
Given that the diameter of the Ferris wheel is 18 meters, we can calculate the circumference as follows:
C = π * d
C = 3.14 * 18
C ≈ 56.52 meters
So, the circumference of the Ferris wheel is approximately 56.52 meters.
Next, we need to calculate the distance traveled for two revolutions. Since one revolution covers the circumference of the Ferris wheel, the total distance for two revolutions is twice the circumference:
Total distance = 2 * C
Total distance = 2 * 56.52
Total distance ≈ 113.04 meters
Therefore, the rider would travel approximately 113.04 meters during two revolutions on the Ferris wheel.
