For instance, if we had a pizza with a radius of 6 inches…
6 inches

To find the area of the pizza, we would use the equation:
A = π times r2
6 inches

Plugging in the values for each item:
A = (3.14) times (6 inches)2
6 inches

Simplifying a little bit:
A = (3.14) times (36 inches2)
6 inches

That means the area of the pizza is 113.04 square inches (in.2).
A = 113.04 inches2
6 inches
