    You can compare areas with just r^2 you don’t even need pi. So the math is easy.

      A pizza is larger than two of another just before it hits 1.5 times the radius (sqrt 2 times, to be exact, about 1.41). So if the radius is 1.5 times bigger, like in the OP, you always know it’s more than twice the area.
