Circumference of a circle is found with the equation
C = 2 × pi × r
where r is the radius. So for your problem...
C = 2 × 3.14 × 4
C = 25.12 meters
If we join the Center with different corners of the polygon,we find 10 Isoceles triangle with equal side=9.14cm, Making an angle of 36° between the equal sides.
Area of 1 triangle= a*b*sinC/2
= 9.14*9.14*Sin36°/2
= 9.14*9.14*0.587/2
=24.51 cm^2
Area of 10 triangle= 24.51*10
= 245.1cm^2
Answer:
Increasing on the interval(s) 
Decreasing on the interval(s) 
Step-by-step explanation:
Anytime the graph is going upward, the function is increasing. However, anytime the graph goes down, the function is decreasing. Look at the image below for further reference. Also, when the function is increasing, the slope is positive, and when the function is decreasing the slope is negative.
The increasing interval of the graph is -3
The decreasing interval of the graph is 0.5
Since the values are in the middle of the interval, it automatically becomes the answer.
The mean is the average. To find it, you add all of the numbers together.
2 + 8.7 + 11.9 + 3.3 + 4.2 + 2.2 + 13.4 = 45.7
Now you divide the total by the amount of numbers you added. Because you added 7 numbers, you divide 45.7 by 7.
45.7 ÷ 7 = 6.52 (This is the mean.)
To find the median you have to put all of the numbers in order of least to greatest.
2 2.2 3.3 4.2 8.7 11.9 13.4
The median is the number in the very middle. In this case, it is 4.2.
