The circumference of the 12-inch pizza is twice as big as the 6-inch pizza.Determine the circumference (C) of both pizzas.C = pi x d, where d is the diameter6-inch pizzaC = pi x 6 in = 18.85 in12-inch pizzaC = pi x 12 in = 37.70 inDivide the circumference of the larger pizza by the circumference of the smaller pizza.37.70/18.85 = 2
Area of a 14 inch pizza = 43.98in2. Area of a 12 inch pizza = 37.70in2. Difference between the two = 6.28in2.

The area of a circle with a 12-foot circumference is about 11.46 square feet.
A = pi r2 = 2 x aprox 3.141593 x 122 = 904.8 square inches C = 2 x pi x r = 2 x aprox 3.141593 x 12 in = aprox 75.4 inches
