To calculate the area that a ring pizza we need two values: the number Pi i beg your pardon is equal to 3.14159.. And the diameter or size of the pizza. Most usual pizza sizes and also their particular diameter worths are: small - 10", tool - 12", big - 14", X-large - 16", and also XX-large or Jumbo - 18".To begin, us calculate the square of the diameter (or simply multiply the diameter value by itself), climate multiply that by Pi, and also then division the an outcome by 4.

The formula to calculation the area A that a round pizza is shown below:A = 3.14159 × d 2 ÷ 4where d is the diameter of the pizza.

The area that a rectangular pizza can be figured out by multiply the length L by the broad W:A = l × W To calculate the area the a part we require to recognize the length r of the part side (the radius of the pizza) and also the main angle θ between sides (in degrees):As = ( θ ÷ 360 ) × 3.14159 × r 2Alternatively, if the variety of slices the pizza was cut into is known, the area the a slice have the right to be calculated by dividing the area that the totality pizza by the number of slices.
