Each slice is about 25.45 square inchesArea = pi r2 = pi (182) = 254.47 square inchesor arc = 5.4 inches
The answer is 6 inches.
If they are the diameters of the pizzas then:- Each slice of the 7 inch pizza is about 9.62 square inches Each slice of the 9 inch pizza is about 7.95 square inches

The answer is 6 inches.
28.00563 inches, roughly equal to 28 inches
That is approximately 14.14 square inchesArea of pie = pi r2 = pi (62) = about 113.1 square inches113.1 / 8 = about 14.137
If they are the diameters of the pizzas then:- Each slice of the 7 inch pizza is about 9.62 square inches Each slice of the 9 inch pizza is about 7.95 square inches
The total area of pizza is given by the formula A = pi x r2 where r is the radius. So the total area of the pizza is approximately 144(pi) or 452.39 square inches, and if cut into 16 pieces will yield approximately 28.27 square inches per slice.
Area of a circle = (pi) x (radius)2 Radius = 1/2 the diameter = 5 inches Area = (pi) x (5)2 = 25 pi = 78.54 square inches (rounded)
