10.11 Area of Sectors and Segments
Here you’ll learn how to find the area of a sector or a segment of a circle.
What if you wanted to find the area of a pizza, this time taking into consideration the area of the crust? In another
Concept, we found the length of the crust for a 14 in pizza. However, crust typically takes up some area on a pizza.
Leave your answers in terms ofπand reduced improper fractions.
a) Find the area of the crust of a deep-dish 16 in pizza. A typical deep-dish pizza has 1 in of crust around the
toppings.
b) A thin crust pizza has^12 - in of crust around the edge of the pizza. Find the area of a thin crust 16 in pizza.
c) Which piece of pizza has more crust? A twelfth of the deep dish pizza or a fourth of the thin crust pizza?
After completing this Concept, you will be able to answer these questions.
