Enter the diameter of the pizza (in) into the Pizza Area Calculator. The calculator will evaluate the Pizza Area. 

Pizza Area Formula

The following two example problems outline the steps and information needed to calculate the Pizza Area.

PA = pi*(PD/2)^2
  • Where PA is the Pizza Area (in^2)
  • PD is the diameter of the pizza (in) 

To calculate the pizza area, square half of the diameter, then multiply the result by pi.

How to Calculate Pizza Area?

The following example problems outline how to calculate Pizza Area.

Example Problem #1:

  1. First, determine the diameter of the pizza (in).
    • The diameter of the pizza (in) is given as: 14.
  2. Finally, calculate the Pizza Area using the equation above: 

PA = pi*(PD/2)^2

The values provided above are inserted into the equation below and computed.

PA = pi*(14/2)^2 = 153.93 (in^2)

Example Problem #2: 

For this problem, the variables required are provided below:

diameter of the pizza (in) = 16

${V2} = ${number 4}

Test your knowledge using the equation and check your answer with the calculator..

PA = pi*(PD/2)^2 = ?
