Question

A pizza is cut into twelve pieces. Describe the steps you would take to find the area of one slice of the pizza.

Answer 1

Steps (assuming the pizza is a circle and cut into 12 equal slices):

1. Measure the pizza’s radius r (or measure the diameter d and compute r = d/2).
2. Compute the area of the whole pizza: A_total = π r^2.
3. Divide that area by 12 to get the area of one slice: A_slice = (1/12) π r^2.

Alternate (using central angle): each slice has central angle 360°/12 = 30°, so
A_slice = (30°/360°)·π r^2 = (1/12)·π r^2.

Example: if the diameter is 12 in, r = 6 in, so A_slice = (1/12)·π·6^2 = 3π in^2 ≈ 9.42 in^2.

Remember to include units and round as needed. If slices are not equal, measure the slice’s central angle θ and use A_slice = (θ/360)·π r^2.
