Answer: The area of the whole pizza can be found using the formula for the area of a circle:

A = πr^2

where r is the radius of the pizza, which is half the diameter. So, for a pizza with a diameter of 16 inches, the radius is 8 inches:

r = 8 inches

A = π(8 inches)^2

A = π(64 square inches)

A = 201.06 square inches (rounded to two decimal places)

If one person ate one eighth of the pizza, then the remaining area of the pizza is:

remaining area = total area - eaten area

eaten area = (1/8) × total area

remaining area = total area - (1/8) × total area

remaining area = (7/8) × total area

So, the remaining area of the pizza is:

remaining area = (7/8) × 201.06 square inches

remaining area ≈ 175.84 square inches

Therefore, the answer is B) 175.84 square inches.
