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 =
1 mile = 1.61 kilometers
4 miles = 6.44 kilometers
D ( -b, h)
E ( b, h)
F ( b, -h)
G ( -b, -h)
from 0 to E, x=b, from 0 to DG, x= -b
from 0 to DE, y=h, from 0 to GF, y= -h
