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 =

multiply top eqatyion by -1 and add to 2nd
9x-2y=24
<u>-x+2y=8 +</u>
8x+0y=32
8x=32
divid both sides b y8
x=4
sub back
-x+2y=8
-4+2y=8
add 4 to both sides
2y=12
divide both sides by 2
y=6
(x,y)
(4,6)
We can solve this pretty easily using a proportion where x equals the number of cloudy days in the year:
2/5 = x/365
Now cross multiply:
730 = 5x
And finally divide both aides by five:
146 = x
So 146 days of the year were cloudy.
