The diameter is 48 feet. The radius is half of the diameter, so it is 24 feet. The area can be found using the formula pi r ^ 2. So, the area is 576 pi
Answer: i have absolutely no idea
Step-by-step explanation:
You need to include how wide the walls are. but once you find how wide the walls are (X) then multiply it by how tall a the walls are (8 feet) and you will get the area of one wall. Take that answer and multiply it by 3 then multiply that by how much the paint costs
Answer: 3424.28
Step-by-step explanation:
Given data : 378, 361, 350, 375, 200, 391, 375, 368, 321
Number of data values = 9
Mean :![\overline{x}=\dfrac{\sum^n_{i=1} x_i}{n}](https://tex.z-dn.net/?f=%5Coverline%7Bx%7D%3D%5Cdfrac%7B%5Csum%5En_%7Bi%3D1%7D%20x_i%7D%7Bn%7D)
![\\\\=\dfrac{378+361+350+375+200+391+375+368+321}{9}\\\\=\dfrac{3119}{9}\approx346.56](https://tex.z-dn.net/?f=%5C%5C%5C%5C%3D%5Cdfrac%7B378%2B361%2B350%2B375%2B200%2B391%2B375%2B368%2B321%7D%7B9%7D%5C%5C%5C%5C%3D%5Cdfrac%7B3119%7D%7B9%7D%5Capprox346.56)
Variance = ![\dfrac{\sum^n_{i=1} (x_i-\overline{x})^2}{n-1}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Csum%5En_%7Bi%3D1%7D%20%28x_i-%5Coverline%7Bx%7D%29%5E2%7D%7Bn-1%7D)
![\sum^n_{i=1} (x_i-\overline{x})^2 = (31.44)^2+(14.44)^2+(3.44)^2+(28.44)^2+(-146.56)^2+(44.44)^2+(28.44)^2+(21.44)^2+(-25.56)^2\\\\=27394.2224](https://tex.z-dn.net/?f=%5Csum%5En_%7Bi%3D1%7D%20%28x_i-%5Coverline%7Bx%7D%29%5E2%20%3D%20%2831.44%29%5E2%2B%2814.44%29%5E2%2B%283.44%29%5E2%2B%2828.44%29%5E2%2B%28-146.56%29%5E2%2B%2844.44%29%5E2%2B%2828.44%29%5E2%2B%2821.44%29%5E2%2B%28-25.56%29%5E2%5C%5C%5C%5C%3D27394.2224)
Variance = ![\dfrac{27394.2224}{8}=3424.2775\approx3424.28](https://tex.z-dn.net/?f=%5Cdfrac%7B27394.2224%7D%7B8%7D%3D3424.2775%5Capprox3424.28)
B is the answer to the question
