2 x 5/ 50 x 18
10 / 900
Divide both by 10
1/90
Answer:
y=-8
x=-23
Step-by-step explanation:
see attached document
Capetown as it has higher temp.
The relationship of arcs is:
S '/ S = ((1/9) * pi * r) / (2 * pi * r)
Rewriting we have:
S '/ S = ((1/9)) / (2)
S '/ S = 1/18
Therefore, the area of the shaded region is:
A '= (S' / S) * A
Where A: area of the complete circle:
Clearing we have:
A = (A ') / (S' / S)
Substituting:
A = ((1/2) pi) / (1/18)
A = ((18/2) pi)
A = (9pi)
Answer:
The area of the circle is:
A = (9pi)
11. 2x-6 = 8
2x=14
x= 7
12. 3y= 24
y=8
13. 5j-3= 772
5j= 775
J= 155
14. 2g+2= 3g+6
-4= g
15. 24=4/3x
4x = 72
X= 18
