Answer:
Volume=355 cm³
Step-by-step explanation:
I assume it should be 10 cm, not 10 m. If it is 10 m, everything will have to be adjusted.
Circumference = 2r
10=2r
10÷2=r
1.59=r
V=r²h
V=(1.59)(71)
v=355

Answer: The value of the center increases and the distribution has a smaller spread.
Step-by-step explanation:
Re - arranging the first value in ascending order , we have :
12 ,14, 16 , 19, 21 , 22 , 28 , 32
Median = 19 + 21 / 2
= 40/2
= 20
Also calculating the standard variation in order to know the spread , we need to first of all calculate the mean
Mean = 12 + 14 + 16 + 19 + 21 + 22 + 28 + 32 / 8
Mean = 164/8
Mean = 20.5
Therefore to calculate the standard deviation, we need to calculate the variance, which is

/ 8
Variance = 328/8
Variance = 41
Standard deviation =
S.D =
S.D = 6.4
Also re arranging the second values , we have :
20 , 24 , 25 , 31
Median = 24 + 25 / 2
Median = 49/2
Median = 24.5
Calculating the S.D using the same format , the S.D = 3.9
Comparing the two we can conclude that the value at the center increases and the distribution has a smaller spread
In this question, it is given that the base radius is 2 , height is 6 and the value of pi is 3.14 .
And we have to find the volume of the cylinder, and for that, we have to use the following formula
Substituting the values of pi,r and h, we will get
It is given in the question that
Ms. Velez will use both x gray bricks and y red bricks to build a wall around her garden. Gray bricks cost $0.45 each and red bricks cost $0.58 each. She can spend up to $200 on her project, and wants the number of red bricks to be less than half the number of gray bricks.
Maximum she can spend is $200. That is
And
And that's the required inequalities .
