I think the other comments are a common case of blindly applying math without common sense/logic.

Its clear the angles on the photo are incorrect/misleading. You cant cut a pizza evenly into 65deg slices. I therefore believe the 6inch slice is supposed to be 60deg (6 slices per pizza). And the 7inch slice is supposed 45deg (8 slices per pizza):

60/360 * pi * 62 = 18.84 inch2

45/360 * pi * 72 = 19.24 inch2

Thats 2% more area for the 7inch.

Also, alot of people prefer to maximise the toppings and not crust. If we assume 0.5 inches of crust per pizza then the 7inch slice has an even greater proportion of toppings:

60/360 * pi * 5.52 = 15.83 inch2

45/360 * pi * 6.52 = 16.59 inch2

Thats 5% more toppings.

Either way it doesnt seem worth the 13% price hike

Nope, not logical

Perhaps they also offer a 35degree slice as part of something else !
