Section 2.6 Area of a Part of a Circle
Key Inquiry Questions 2.6.1.
How do we use the concept of the area of a part of a circle in real life?
In Grade 8, you learned how to find the area and arc length of a sector.
Now, you’ll go a step further and discover how to find the area of different parts of a circle.
-
the area of an annulus (a ring shape),
-
-
the area of an annular sector (a slice of a ring),
-
and the area where circles overlap.
