haha ya sorry

directrix · Answer

pi * 6^2 - pi * 5^2 = 36 pi - 25 pi = 11 pi = 34.557 approx

Area of a circle = pi r^2. The diameter is twice the radius. Assume the amount of pizza toppings is the same.

It's just a ratio of 12 squared to 10 squared ("squared" means "to the second power"), so 144 to 100, or 44% bigger by area.

Another way to say it is "it is 1.44 times as large."
