A point on the rim would travel a distance equal to the circumference of the wheel. The wheel has diameter 42 in, so the circumference is 42π in.
2π radians corresponds to one complete revolution of the wheel. So the wheel has a linear speed of
(3 rad/s) * (42π/2π in/rad) = 63 in/s
Answer: 0.4 meters per hour.
Step-by-step explanation:
The rate of change of distance with respect to time is known as speed.
Formula :![\text{Rate of change}=\dfrac{\text{Change in position}}{\text{Change in time}}](https://tex.z-dn.net/?f=%5Ctext%7BRate%20of%20change%7D%3D%5Cdfrac%7B%5Ctext%7BChange%20in%20position%7D%7D%7B%5Ctext%7BChange%20in%20time%7D%7D)
Given : It's raining outside, and after 1 hour of rain, the water level in Jake's pond is 2 meters. After 3 hours, the water level is 2.8 meters.
i.e. Change in position= 2.8-2=0.8 meters
Change in time = 3-1=2 hours
i.e. ![\text{Rate of change}=\dfrac{0.8}{2}=0.4](https://tex.z-dn.net/?f=%5Ctext%7BRate%20of%20change%7D%3D%5Cdfrac%7B0.8%7D%7B2%7D%3D0.4)
Hence, the rate of change =0.4 meters per hour.
The deepest point of the lake is -922, so to get to the surface of the lake you would need to add 922 feet.
The deepest point of the lake is 11,542 feet above sea level.
To find the surface of the lake add 922 to 11,542.
11542 + 922 = 12,464 feet
