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
