Circumference: 18.84 m
Area: 28.26
Explanation
For circumference, use the formula
*d, where d=the diameter(the radius times 2).
For area, use the formula 
, where r=the radius. Make sure to square the radius first before multiplying by pi!
A good way to remember these formulas is Cherry(circumference) Pi(
) is Delicious(diameter) and Apple(area)
("are too")
Mean is the average number in the data set.
To get the average we first add all the numbers.
After we add all these numbers we then divide by the number of numbers in the data set.
So we do 22+18+38+6+24+18 which is equal to 126 there are six numbers so we divide 126 by 6. This gives us a mean of 21.
ANOTHER EXAMPLE:
Another example of this is the data set (4,65,7,34,5)
We first add all the numbers and get 115 then we divide by 5 and get 23 as the mean.
Answer:
Therefore the measur angle ACB

Step-by-step explanation:
Given:
ΔABC is a right Triangle at ∠A = 90°
AB = 15 ....Side Opposite to ∠ACB
AC = 8 ....Side Adjacent to ∠ACB
To Find:
m∠ACB = ?
Solution:
In Right Angle Triangle ABC, Tangent Identity we have

Substituting the values we get

Therefore the measur angle ACB

Answer:
Step-by-step explanation:
y = -x - 1
the slope here is -1. A parallel line will have the same slope
y = mx + b
slope(m) = -1
(5,-5)....x = 5 and y = -5
now we sub....we are looking for b, the y int
-5 = -1(5) + b
-5 = -5 + b
-5 + 5 = b
0 = b
so ur equation is : y = -x + 0....or just y = -x
