Answer:

Step-by-step explanation:
Given:
Length of radius of circle = 5 feets
Length of perpendicular bisector = 4 feets
To find:
Area of the shaded portion of the circle
Solution:
As OD is perpendicular bisector of AB,


Area of
= 1/2 (base) × (height) =
square feets
Area of sector AOBC =
square feets
Here, r denotes radius of circle
So,
Area of shaded portion = Area of sector AOBC - Area of
=
Answer=7/8
7x3=21
12x2=24
21/24=7/8
Answer:
a= -1
