Fill in the Blanks
An ellipse is described by using an endless string which is passed over two pins. If the axes are 6 cm and 4 cm, the length of the string and distance between the pins are ____________.
Answer :
a = 6, a2 = 36
b = 4, b2 = 16
b2 = a2 (1 - e2)
16 = 36 (1 - e2)
4 = 9 (1 - e2)
Hence the length of strings and distance between the pins is 
&
respectively.
