circumference (the crust)= 3.14(pie)*radius^2

C=3.14*12^2 (12 inch)

C=3.14*8^2 (8 inch)

Then subtract the answer of the 8 inch diameter pizza from the answer of the 12 inch diameter pizza.

circumference (the crust)= 3.14(pie)*radius^2

C=3.14*12^2 (12 inch) = 452.16

C=3.14*8^2 (8 inch)=200.96

452.16 minus 200.96 = 251.2 in in diameter
