Question

What is minor axis length for ellipse \((\frac{x}{25})^2+(\frac{y}{16})^2\)=1?

(a) 5 units

(b) 4 units

(c) 8 units

(d) 10 units

This question was addressed to me in an interview for internship.

The origin of the question is Conic Sections topic in section Conic Sections of Mathematics – Class 11

Answer 1

Right option is (c) 8 units

For explanation I would say: Comparing the equation with \((\frac{x}{a})^2+(\frac{y}{b})^2\)=1, we get a=5 and b=4.

Minor axis length = 2b = 2*4 = 8 units.
