<u>Answers with step-by-step explanation:</u>
1. Area of sector 1 = 
2. Area of sector 2 = 
3. Area of sector 3 = 
4. Area of sector 4 = 
5. Arc length of sector 1 = 
6. Arc length of sector 2 = 
7. Arc length of sector 3 = 
8. Arc length of sector 4 = 
add the 2 numbers and then divide by 2
Coordinates of the center you can find from
x-3=0 and y+5=0
x=3 and y=-5
(3,-5) is the center of the circle.
25 is a square of the radius.
r²=25, so
r=5
Center (3,-5), r=5
So, the answer is D.
I believe the answer is c. 14
