If a 8 inch pizza cost 8 and a 16 inch cost 16 which one is cheaper?
Well because 8¢ is less than 16¢, it would be the 8 inch pizza...Now if you are wondering which one is better value, the 16" pizza has 4 times the area of the 8" pizza, but is only 2 times the cost, so obviously the 16" pizza is a better bang for the buck, so to speak.
If a seven inch pizza cost 4.00 and the price of the 14 inch is proportional to the cost of the seven inch how much would the fourteen inch pizza cost?
The area of the pizza inceases as the square of the radius (or diameter). Assuming the thickness remains the same, then the volume also increases as the square of the radius. So, double radius implies quadruple area implies quadruple cost.
How many square inches are in a 16 inch pizza?
The area of a 16" pizza is 201.2 sq inches which is 0.1297 sq metres
What is the area of a 20 inch pizza?
If that is the diameter, divide by 2 to get the radius. Then use the formula: area = pi x radius2.
Are two 10 inch pizzas the same size as one 20 inch?
No Side by side the total would be 20 inches but there would be a space at top and bottom Assuming they are the same depth, then the comparison is between the areas. As the lengths are in the ratio of 10:20 = 1:2, their areas are in the ratio 1²:2² = 1:4 Thus the 20 inch pizza has four times the area of a 10 in pizza, ie a 20 inch pizza is the same as FOUR 10 inch pizzas.
