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

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

suck a

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.

To find out the difference in crust between a large pizza with a 12-inch diameter and a small pizza with an 8-inch diameter, we need to calculate the difference in their crust lengths. The crust length is the circumference of the pizza.

The formula to calculate the circumference of a circle is C = π * d, where C represents the circumference, and d represents the diameter.

For the large pizza:
C_large = π * d_large
C_large = π * 12 inches

For the small pizza:
C_small = π * d_small
C_small = π * 8 inches

To find the difference between the two crust lengths (C_large - C_small), we subtract the smaller crust length from the larger crust length.

(C_large - C_small) = (π * 12 inches) - (π * 8 inches)
(C_large - C_small) = π * (12 inches - 8 inches)
(C_large - C_small) = π * 4 inches
(C_large - C_small) ≈ 12.57 inches

Therefore, a large pizza with a 12-inch diameter has approximately 12.57 more inches of crust than a small pizza with an 8-inch diameter.
