Answer:
infinite solutions
Step-by-step explanation:
Find the circumference and multiply it by 3.
C = pi * d
C = 3.14 * 21
C = 65.94
So it travels 65.94 inches in 1 revolution.
65.94 * 3 = 197.82
So it travels 197.82 inches in 3 revolutions.
The question is really quite easy. You just have to find the distance between the sea level and the point down the water. Make an illustration about the problem to visualize it better. The picture is shown in the attached picture. The distance we want to get is denoted as x. The solution is as follows:
x = 4.7 - 0.5 = 4.2 m
Hope this helps!
