B (16.76)

Work Step by Step

Given Information: The Diameter of the Pizza is 16, and it has 12 slices. Area of a Slice = $\frac{1}{12}$ of the Area of the Circle Area of a Circle = $\pi (r)^{2}$, so the Area of a Slice = $\frac{1}{12} (\pi (r)^{2})$ Radius (also known as r) = $\frac{1}{2}$ Diameter (d) Diameter = 16, so Radius = 8 Area of the Pizza = $\pi (r)^{2} = (8^{2})\pi = 64\pi$ Area of a Slice = $\frac{64\pi}{12} \approx 16.7551608191$ This is a multiple choice question, and 16.7551608191 is closest to answer B, which is 16.76.
