Answer:

B. 175.84 square inches

Explanation:

The pizza is shaped like a circle

Area of a circle = π r² where r is the radius

r = d/2 where d = diameter

Here d = 16 in

r = 16/2 = 8

Total area of pizza = π · 8² = 64 π

If 1/8th of the pizza was consumed balance = 1-1/8 = 7/8

7/8 of the total area = 7/8 x 64π = 56π = 175.84 square inches

This is the area of the remaining portion of the pizza
