How much more crust does a large pizza with a diameter of 12 inches have than a small pizza with an 8-inch diameter?

  • Math -

    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.

  • Math -

    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
