Is the 8 inches of the Pizza the diameter or circumference? Is the 8-inches of the box the area of side length? If the diameter if the pizza and the side length of the box are both 8-inches, then the pizza will barely fit. If the circumference of the pizza is 8 inches, that means that the diameter is 8/pi = 2.546..... and that would fit in a box with side lengths of 8-inches. If the box's area is 8-inches, that means the side lengths are the square root of 8=2.828.... A pizza of diameter 8-inches won't fit, but a pizza of circumference of 8-inches will.
That would depend on what you mean by "five inch circle".
There are 100*pi square inches in a 20 inch diameter circle
The area of a circle with an 8 inch diameter is approximately 50.27 square inches.
I suggest you divide the 14 inches and the 11 inches by 2 to get the radius (presumably, the numbers refer to the diameter). Then you can calculate the area using the formula for a circle, and compare.
490.9 square inches for a 25-inch diameter circle.
That would depend on what you mean by "five inch circle".
Area of a 12-inch circle: 113.1 square inches.Area of a 16-inch circle: 201.1 square inches.
There are 100*pi square inches in a 20 inch diameter circle
No because there are about 64 square inches in the 9 inch pizza and about 254 square inches in the 18 inch pizza.
In a circle with a diameter of 4, there would be approximately 12.56 square inches in the circle.
To calculate the price per square inch of pizza, you will need to know the area if the pizza in square inches, and the price of the pizza. For example, let's say you have a 12 inch pizza that cost 5 dollars. Pizzas are generally measured in diameter, so the diameter of the pizza is 12 inches, and the radius is half of that, or 6 inches. The formula for the area of a circle is (1/2)(pi)(radius)2, which, in this case, is (1/2)(pi)(6 in)2, or about 56.5 in2. We now know the area and the price. The formula for price per square inch is what is sounds like: (price)/(area in in2). In this case, it is (5)/(56.5), or about .089 dollars. So this pizza costs about 9 cents per square inch.
The area of a circle with an 8 inch diameter is approximately 50.27 square inches.
Area of a 14 inch pizza = 43.98in2. Area of a 12 inch pizza = 37.70in2. Difference between the two = 6.28in2.
A 1.25-inch diameter circle contains 1.227 square inches.
The area of a 14-inch circle is: 153.9 square inches.
49pi-36pi= 13pi= 40.8 square inches
