Question of the Day for May 17 – 2010

Question

We have an angle of 3 degrees.How big will it look through a glass that magnifies things four times?

Solution:

The measure of the angle will not change because though magnifying glass will increase the length of the arc  of the angle but at the same time it will also increase the radius proportionally.So the ratio of the length of the arc to radius (and hence  the circumference of the circle) remains the same and does not change the angle.
