The formula for the area of a circle is
We know the diameter, and the radius is half of the diameter. So the radius is 9. Now we plug that into the formula.
So the answer is B, 81 pi square feet
Answer:
2. scale factor 2 | x = 4.5
3. scale factor 1.5 | x = 12
Step-by-step explanation:
Answer:
Step-by-step Explanation:
The 44th percentile, 
, of the given data can be calculated using the kth formula for percentile given as:
where,
i = the ranking or the position of the percentile = ?
k = the percentile = 44
n = total number of the given data values = 23
Plug in the values into the formula to find "i"
Since "I", 10.56, is not an integer, round the number down, and round it up to the nearest integer, then look for the position each occupy in the ordered data set, and find their average.
Thus,
The data occupying the 10th position on the data set = 28.7
11th = 31.1
1627190 there's your answer.
