Answer:
4 seconds
Step-by-step explanation:
Area = PI * radius^2
Circumference = 2 * PI * radius
radius = Circumference / 2 * PI
So, Area = PI * (Circumference / 2 *PI) * (Circumference / 2 *PI)
So, Area = Circumference^2 / (4*PI)
Answer:
the radius is 10 since 10 plus ten is 20
Answer:
≈ 13.98%
Step-by-step explanation:
As the total population is 5769 in the initial period, you must find the percentage that repesents 4963 that is the expected population.
4963/5769=0.8602
Then you multiply it by 100 to transform it into percentage
0.8602*100=86.02%
Then it's just necesary to subtract that from 100% and that numbers is the percentage of decrease
100% - 86.02% = 13.98%
Also you can say that is approximately 14%
260.5 is the median for the data set hope this helps;)
