About 127 inches. use the formula: r squared times 3.14 divided by 2. aka the formula to find area of a circle divided by two because it only covered 30 mins
2 tens, 4 ones, 3 tenths, 5 hundredths, 7 thousandths
9,11,13,20
20 -9 = 11
Range: 11 so its not 17
11 + 13 = 24
24/2 = 12
Median: 12 so its not 10
9+ 11 + 13 + 20 = 53
53/4= 13.25
Mean: 13.25 so its not 12
IQR: 6.5 so its not 7 or 12

Step-by-step explanation:
Let the numbers be ![a, b\ and\ c.](https://tex.z-dn.net/?f=a%2C%20b%5C%20and%5C%20c.)
![a = 17](https://tex.z-dn.net/?f=a%20%3D%2017)
![b * c = 28](https://tex.z-dn.net/?f=b%20%2A%20c%20%3D%2028)
Required
Determine the possibilities for the other two
The possibilities of the other two (as a product) are:
![1 * 28 = 28](https://tex.z-dn.net/?f=1%20%2A%2028%20%3D%2028)
![2 * 14 =28](https://tex.z-dn.net/?f=2%20%2A%2014%20%3D28)
![4 * 7 = 28](https://tex.z-dn.net/?f=4%20%2A%207%20%3D%2028)
<em>All possible combinations are (where order is not important): 17 1 28, 17 2 14 and 17 4 7</em>
Answer:
B. 15 + 5√3.
Step-by-step explanation:
The ratio of the sides in a 30-60-90 triangle is 1:√3:2.
So here the lengths of the sides are 5, 5√3 and 10.
Perimeter = 15 + 5√3.
