Hi,
Area of the circular pizzas = pi%2Ar%5E2 where r is the radius of the pizza
Using pi+=+3.14 and giving answer to nearest whole number
A%5B12%5D+=+pi%2A6%5E2+=+3.14%2A36 = 113 in^2
A%5B14%5D+=+pi%2A7%5E2+=+3.14%2A49 = 154 in^2
A%5B16%5D+=+pi%2A8%5E2= 3.14*64}}} = 201 in^2
how many more square inches are in a 14 inch pizza than in a 12 inch pizza
154in^2- 113in^2 = 41in^2
Area of the Square Pizza = 15^2 = 225in^2 More pizza in the square pizza
Which has more crust (crust being on the perimeter/circumference)
P%5BS%5D+=+60in
C%5B16%5D+=+pi%2Ad+=+pi%2A16+=+3.14%2A16+=+50.3in+
Square Pizza has more crust
