Question 823674: the ellipse used to form a lithotripter has a major axis of 12 ft. and a minor axis of 5 ft. how far from the center are the foci? Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! ---
f = sqrt( a^2 - b^2 )
a = major radius
b = minor radius
---
f = sqrt( 6^2 - 2.5^2 )
f = sqrt( 29.75 )
f ~= 5.4543561
---
answer:
the distance from the center of the ellipse to either foci is about 5.454 ft
