If the c 2 and a 8 then what is the eccentricity?

To determine the eccentricity of a conic section, we typically use the formula ( e = \frac{c}{a} ), where ( c ) is the distance from the center to the focus and ( a ) is the distance from the center to a vertex. If ( c = 2 ) and ( a = 8 ), then the eccentricity ( e ) is calculated as ( e = \frac{2}{8} = \frac{1}{4} ). Thus, the eccentricity is ( 0.25 ).
