Answer:
Perimeter = 21 units
Volume = 110 cubic units
Step-by-step explanation:
Let the center of circle be (x,y).
![(x+2)^{2} +(y-7)^{2} = (x)^{2}+(y+2)^{2}](https://tex.z-dn.net/?f=%28x%2B2%29%5E%7B2%7D%20%2B%28y-7%29%5E%7B2%7D%20%3D%20%28x%29%5E%7B2%7D%2B%28y%2B2%29%5E%7B2%7D)
4x - 18y = - 45
![(x)^{2}+(y+2)^{2}=(x-2)^{2}+(y-2)^{2}](https://tex.z-dn.net/?f=%28x%29%5E%7B2%7D%2B%28y%2B2%29%5E%7B2%7D%3D%28x-2%29%5E%7B2%7D%2B%28y-2%29%5E%7B2%7D)
4x + 8y = 4
x + 2y = 1
Solving these 2 equations,
4 - 26y = -45
y = ![\frac{49}{26}](https://tex.z-dn.net/?f=%5Cfrac%7B49%7D%7B26%7D)
x = ![\frac{-36}{13}](https://tex.z-dn.net/?f=%5Cfrac%7B-36%7D%7B13%7D)
radius = 3.35
Perimeter = 2
= 21 units
Volume of cylinder = ![\pi r^{2} h](https://tex.z-dn.net/?f=%5Cpi%20r%5E%7B2%7D%20h)
We have to add the volumes of the cylinders.
Volume of smaller cylinder =
= 8![\pi](https://tex.z-dn.net/?f=%5Cpi)
Volume of larger cylinder = 27 ![\pi](https://tex.z-dn.net/?f=%5Cpi)
Total volume = 35
= 110 cubic feet
Cos 270 = 0 and sin 270 =-1
so -5i from a part.
Can you mark as BREINLEST
Answer:
The second answer is decreases.
Step-by-step explanation:
As X -value increases, the y-value decreases. If you reply back with the options for the first half of the question I'll do my best to answer that as well
1/5, 2/10, 3/15, 4/20, 5,25, and on going up a number example (...6,7,8,9,10) and up 5 example (...30,35,40,45)
