The seismic wave of an earthquake is represented by the equation r = 13.2 sin, where r is measured in miles. What does the 13.2 in the equation represent?
The coefficient 13.2 represents the ____ of the circular area affected by the seismic wave.
Circumference, diameter, or radius?
(The answer is diameter, but no one has asked this question yet, so I'm putting it out there on the internet for the other people who get this question on Edge in the future)
