Okok so we can calculate area, but the real thing we want is volume. However, if we were to assume both slices have the same thickness, then we can simply approach the problem using area of a sector. For the sake of this problem, I'll also assume that the pepperoni slices are equal in amount and volume for both slices.(They clearly aren't but too lazy to google volume of a pepperoni slice rn. Also I don't consider toppings as important as the pizza base.) Pizza is simply a circle of dough before it is made. In order to create the crust, a small portion of the circle dough's edge is folded towards its center. If we were to "undo" this fold and revert the pizza slice back into dough, we could calculate the volume of the crust without having to use anything like integration. My approach to this problem is to estimate a small amount in which you'd add to the radius of each slice. By doing this, we pretend the pizza does not have a crust and is completely a cylinder. I'd say add 0.5in to each slice. At this point, you can just treat the pizza like a circle since we're assuming that both slices have the same thickness. You can ignore everything above since it's just random nonsense I was spewing about volume. If you want to solve this problem in terms of area, convert each angle into radians and use the area of a sector formula: A = 1/2 x angle x r^2. Use division to determine how much each square inch of the pizzas is worth and compare the two results. You should have your answer by then.
