Answer:
![490.9\ ft^{2}](https://tex.z-dn.net/?f=490.9%5C%20ft%5E%7B2%7D)
Step-by-step explanation:
we know that
The total area is equal to
![A=10(h)+2\pi r(h)+10(h)](https://tex.z-dn.net/?f=A%3D10%28h%29%2B2%5Cpi%20r%28h%29%2B10%28h%29)
we have
![h=9\ ft](https://tex.z-dn.net/?f=h%3D9%5C%20ft)
![r=5.5\ ft](https://tex.z-dn.net/?f=r%3D5.5%5C%20ft)
![\pi=3.14](https://tex.z-dn.net/?f=%5Cpi%3D3.14)
substitute
![A=10(9)+2(3.14)(5.5)(9)+10(9)](https://tex.z-dn.net/?f=A%3D10%289%29%2B2%283.14%29%285.5%29%289%29%2B10%289%29)
![A=490.9\ ft^{2}](https://tex.z-dn.net/?f=A%3D490.9%5C%20ft%5E%7B2%7D)
Answer:
79/120
Step-by-step explanation:
Answer:
6.7
Step-by-step explanation:
10% of 30000
10/100 x 30000
0.10 x 30000
=3000
In order to find how long you have to divide 20k with 3k
20000/3000 = 6.66666667
Round it up and you get 6.7
Answer:
A=5
B=4
Step-by-step explanatation
so the 3ft at the front and the 8ft at the back, you do 8-3 which is 5 which will be A and on the side, it is 8ft and since the corner angle is 4ft then B will be 8-4 which is 4
Answer:
25
Step-by-step explanation:
2(25+20)=90. 25 plus 20 is 45 and 45 times 2 is 90
