You measure it with the tape ruler thing or use pi (3.1415937) times the radius or the diameter. I forgot which one.
The circumference c of any circle with diameter d is d X (pi). In this instance, 12 inches (3.14) = 38 inches, to the justified number of significant digits.
Area of pizza: 64pi square inches.
Assuming the "18 inches round" refers to the circumference, the area is 25.8 sq inches.
21.27"
NO.
You need to use the formula for solving the diameter of a circle which is C = pi * D = 3.1416 * 14 = 43.98 inches (approx)
The circumference is 31.14 inches, approx.
5 inches x 3.1416 = 15.7 inches
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.
The circumference c of any circle with diameter d is d X (pi). In this instance, 12 inches (3.14) = 38 inches, to the justified number of significant digits.
Circumference of a circle = pi DCircumference of the big one = 12 piCircumference of the small one = 8 piDifference = (12 pi - 8 pi) = (12 - 8) pi = 4 pi = 12.5664 inches (rounded)
The circumference of a 5.5 inch pizza is: 17.28 inches.
The circumference of a 29-inch pizza is 91.11 inches.
A large Dominos Pizza is 14 inches.
When advertised the measure of a pizza is its diameter. A 24 inch pizza therefore should have a diameter of 24 inches.
24 inches, because the radius is always 1/2 of the diameter.
Area of pizza: 64pi square inches.
