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

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

Area of a 14 inch pizza = 43.98in2. Area of a 12 inch pizza = 37.70in2. Difference between the two = 6.28in2.

It matter where you buy the pizza

The area of a circle with a 12-foot circumference is about 11.46 square feet.

A = pi r2 = 2 x aprox 3.141593 x 122 = 904.8 square inches C = 2 x pi x r = 2 x aprox 3.141593 x 12 in = aprox 75.4 inches

The circumference of a circle is given by Circumference = pi x diameter. The area of a circle is given by Area = pi/4 x diameter2. Thus for a circle with circumference c = 12 in. The area will equal a = 11.459 in2.

well the formula is 2 pie r

The circumference of a 12-inch round circle in pi is: 12pi

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 12-inch pipe is: 37.7 inches. (C = d x Pi)Since 12 inch pipe is a nominal size and its outside diameter is 12.75 inches, the circumference of 12 inch pipe actually is : 40.035 inches

Circumference = 37.7 inches Diameter = 12 inches

Circumference = 2*pi*r = 12 So radius r = 6/pi Therefore area = pi*r2 = 36/pi = 11.46 sq inches, approx.

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.
