This is the same as finding the area of any circle.
It's the radius squared times pi, where pi is approximately 3.1415927
The formula is: area = pi * r Squared
The radius is half the diameter. So the radius of your 12 inch Pizza is 6 inches.
Squared means multiplying it by itself. So 6 squared is 36.
Multiply 36 by pi and you get 113.0973372 square inches, the area of a 12 inch pizza.
This is the answer to 7 decimal places, probably more precise than you need to know.
Based on same ingredients and amounts I would say an 8" for $7 is better. The costs per inch of pizza is less than that of a 12".
The area of a circle that has a 12-inch diameter is: 113.1 square inches.
The surface area of a 12-inch diameter sphere is 452.39 square inches.The formula for surface area of a sphere is 4*pi*r2 where r=radius
A circle with a diameter of 12 inches has an area of ~113.1 square inches.
About 113.1 square inches.
Area of a 14 inch pizza = 43.98in2. Area of a 12 inch pizza = 37.70in2. Difference between the two = 6.28in2.
Assume both pizzas are cut into eight slices. 3 slices of the 12 inch pizza make an angle of3 pi/4 and area is 1/2 radius squared times angle where radius is 6 inch so area = 42.4 sq in 2 slices of the 16 inch pizza make an angle of pi/2 and area is 1/2 radius squared times angle where radius is 8 inch so area = 50.2 sq in so the two 16 inch slices give you more pizza
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
1 12 inch pizza for 9.99 is the better deal. Whether or not we consider the total volume of pizza purchased or just the surface area of pizza (which reflects how much topping there will be) the proportion between the 12 inch and the two 8 inch pizzas (combined) always results in 9:8. So you are getting slightly more pizza with the 12 inch pizza, and it is cheaper, so it is the better deal. Volume = pi * r2 * h. As r2 for the 12 inch pizza = 62 = 36, this is more than 2 * 42 = 32 by the proportion 36:32, which simplifies to 9:8.
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.
Type your answer here... A 12 inch pizza has a diameter of 12", so the radius = 6". π = 3.14 or use the π button on your calculator Area of a circle = π·r2 = 3.14 × 62 = 113.04 in2 Circumference = 2·π·r = 2 × 3.14 × 6 = 37.68 inches
It matter where you buy the pizza
The weight of a 10-inch pizza can vary depending on the thickness and toppings, but on average, a 10-inch pizza weighs around 10-12 ounces.
Based on same ingredients and amounts I would say an 8" for $7 is better. The costs per inch of pizza is less than that of a 12".
around £11
No because there are about 64 square inches in the 9 inch pizza and about 254 square inches in the 18 inch pizza.
