38 (average) - 29.777 (this year) = 8.223 inches less this year than the average year.
Because 44 is a bigger number than 4 it is 11 times bigger so the difference is larger than a proportional number
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)
Answer:
$77.5
Step-by-step explanation:
7.75*10 = 77.5
Answer:
the shaded region is 12
Step-by-step explanation:
Subtract the area of 4 pie r squared from the area of 2 pie r squared
