How do you find the area of a pizza with a diameter is 18 inches

The area of the pizza with a diameter of 18 inches is 254.34 inches.

Step-by-step explanation:

The formula to find the area of a cirlce is A = pi x r^2 or pi times radius squared.

Second, we need to find our radius. To find the radius we need to divide the diameter by 2 to get the radius. In this case; 18 divided by 2 is 9.

Then, we need to plug the radius in the formula:

A = 3.14 x 9^2

9 squared or 9 times 9 equals 81

Next, multiply 81 by 3.14 and you get 254.34

Lastly, add the units of measurement, which would be inches.
