Geometry and Trigonometry practice question
A circular pizza with a diameter of 16 inches is cut into 8 equal slices. What is the area of one slice, in square inches?
- A. 8πCorrect
- B. 32π
- C. 2π
- D. 16π
Answer: A. 8π
Radius 8, so the whole pizza has area π(8²) = 64π. One of 8 equal slices: 64π/8 = 8π.
Why the other answers are wrong
- B. 32π
- 32π uses the diameter as the radius (256π/8).
- C. 2π
- 2π uses 16π (π × 16) as the whole area.
- D. 16π
- 16π is a quarter of the pizza, two slices.
