Final answer:

The area of the world's largest pizza with a diameter of 131 feet is approximately 13,477 square feet when calculated using the formula A = πr^2 and rounded to the nearest whole number. The closest answer given is 13,471.38 square feet.

Step-by-step explanation:

To calculate the area of a circle, you use the formula A = πr^2 where A is the area, π (pi) is approximately 3.14159, and r is the radius of the circle. The radius is half the diameter, so for a pizza with a diameter of 131 feet, the radius is 131 / 2 = 65.5 feet. Plugging this into the formula, we get A = 3.14159 * (65.5 feet)^2.

A = 3.14159 * 4290.25 square feet

A = 13,477.09 square feet

When rounded to the nearest whole number, the area of the world's largest pizza is approximately 13,477 square feet, which corresponds to option a, 13,471.38 square feet (assuming a minor discrepancy due to rounding).

The number mentioned, 14,687.9 square feet, is incorrect and likely a typo, as the calculation does not match this number.
