directrix · Answer

If you use the area of a circle formula and take a look at the area of a circle of radius 4, and then calculate the area of a circle of radius 1 and quadruple the result of that, it will be clear as to which is larger.

Compare A = pi * (4)^2
with

A = 4 * pi * (1)^2.

Are the results the same?
