We will use formula for circumference of circle:
lets name it as O
O = 2*r * pi
when we express r in this formula we get:
O = 2*2.2*pi
O = 4.4*pi
From this we can see that for given radius, answer is 4.4. The formula only depends on pi and that is what "in terms of pi" means.
Answer:
d. interquartile range
Step-by-step explanation:
the iqr measures the first, second, and third quartile, and the median.
Answer:
4| 7
5| 2 7 8 8
6| 1 6 6 8 8
7| 0 2 2 3 3 5 6 7
8| 4 4 4 5 6 6 7 9
9| 0 1 1 2 3 7
And with the notation 4|7 represent 47
Step-by-step explanation:
For this case we have the following dataset given:
58 52 68 86 72 66 97 89 84 91 91 92 66 68 87 86 73 61 70 75 72 73 85 84 90 57 77 76 84 93 58 47
And if we order the dataset in increasing way we got:
47 52 57 58 58 61 66 66 68 68 70 72 72 73 73 75 76 77 84 84 84 85 86 86 87 89 90 91 91 92 93 97
And if we create the stem plot we got:
4| 7
5| 2 7 8 8
6| 1 6 6 8 8
7| 0 2 2 3 3 5 6 7
8| 4 4 4 5 6 6 7 9
9| 0 1 1 2 3 7
And with the notation 4|7 represent 47
Answer:
WX
Step-by-step explanation:
The distance between vertex X and vertex W is much smaller then from X to Y or W to Y.
You will find the area of the semicircle by finding the area of the circle with a radius of 8.5 mm and the dividing it by 2.
A = pi x r^2
3.14 x 8.5^2
A = 226.865 square mm
226.865/2
113.43
The approximate area of the semi circle is 113.43 mm².
