My teacher said this was badly worded but I still want to solve it:
"Two megaphones shaped like trumpets are attached to the roof of a car, sending sound waves in both directions. These megaphonees were designed to follow a hyperbola with vertices at (0, 8) and (0, -8), and foci at (0, 10) and (0, -10) in a Cartesian plane. The total length of the megaphones is 96cm. What is the diameter of the trumpets?"
The answer is: ~71cm.
Any help would be greatly appreciated!
Thanks in advance!
