When you roll a quarter on its edge, how far does it travel with each complete revolution?
Find the circumference of a quarter.
C = pi * d
To determine how far a quarter travels with each complete revolution when rolled on its edge, we need to consider the circumference of the quarter and the number of revolutions it makes.
The circumference of a circle can be calculated using the formula C = 2πr, where C represents the circumference and r represents the radius of the circle.
First, let's find the radius of the quarter. The diameter of a US quarter is 0.955 inches, so the radius would be half of that, which is 0.955/2 = 0.4775 inches (approximately).
Next, we use the formula to find the circumference: C = 2π(0.4775) = 3.001 inches (approximately).
Now, since each revolution corresponds to one complete trip around the circumference, we can conclude that when a quarter rolls on its edge, it will travel approximately 3.001 inches per revolution.
Therefore, with each complete revolution, a quarter will travel approximately 3.001 inches.
