To explain to my kid I go
18" pizza if it was square thats 18*18 but its not its 1/2 the area so 18*9 = 162
now take a 22 inch pizza cut the middle 18 inches out you're left with a 4 inch wide ring. that ring is 20inches long (18+22/2) so (20*4) so total 22" pizza area is 162+80 242/162 = 1.5 give or take
