You are given the height of a ferris wheel of 125 meters and the diameter of 120 meters. You are also given the rotation speed of 17 minutes per revolution. You are asked to find the angle of rotation per minute.

1 revolution or 1 rotation is equivalent to 360 degrees
360 degrees/ 17 minutes = 21.16 rotation per minute or 21.16 rpm.
RPM or rotation per minute is the measure of the number of rotation completed per minute.

The amplitude is the distance from rest until the peak of its wave or crest. Since the rotation is completed in 17 minutes, therefore its amplitude is π/2

(10.4)2 =<br> to the second power is the 2
Elden [556K]

Answer:

10.4^2 = 108.16

Step-by-step explanation:

10.4^2 = 10.4 * 10.4

10.4 * 10.4 = (10 * 10.4) + (0.4 * 10.4)

(10 * 10.4) + (0.4 * 10.4) = (104) + (4.16)

(104) + (4.16) = 108.16
