To find the area of each pizza slice, you must first find the area of the circle.
The radius is half the diameter, divide 16 by 2 to get 8.
Now, use the formula for the area of a circle (pi x radius squared) to find the area of the pizza.
Pi x 64 (8x8) = 200.96 square inches
Divide 360 by 8 to get the measure of each sector (slice) of the pizza.
360 / 8 = 45
Now, you will want to divide the area of the pizza by the measure of each slice.
200.96 / 45 ~ 4.47 inches squared
The final answer above is the area for each slice of pizza.
