Answer:
25.1 square inches
Explanation:
You want the area of a 1/8 slice of a 16-inch pizza.
Area
The area of a circle is given by the formula ...
A = πr²
where r represents the radius of the circle, half the diameter.
For the 16-inch diameter pizza, the radius is 8 inches, so the area of the whole pizza is ...
A = π(8 in)² = 64π in²
Slice
The area of a slice will be 1/8 of this:
slice area = 1/8(64π in²) = 8π in² ≈ 25.133 in²
The area of a slice of the pizza is about 25.1 square inches.
