Answer:
Perimeter = 21 units
Volume = 110 cubic units
Step-by-step explanation:
Let the center of circle be (x,y).

4x - 18y = - 45

4x + 8y = 4
x + 2y = 1
Solving these 2 equations,
4 - 26y = -45
y = 
x = 
radius = 3.35
Perimeter = 2
= 21 units
Volume of cylinder = 
We have to add the volumes of the cylinders.
Volume of smaller cylinder =
= 8
Volume of larger cylinder = 27 
Total volume = 35
= 110 cubic feet
Answer:
last option is correct answer
Step-by-step explanation:

2x+12 would be the answer
The new height of the water is = 9.34 inches (approx)
Step-by-step explanation:
Given, a rectangular container measuring 20 inches long by 16 inches wide by 12 inches tall is filled to its brim with water.
Let the new height of water level be x inches.
The volume of the container = (20×16×12) cubic inches
=3840 cubic inches
According to the problem,
3840 - (20×16×x) = 850
⇔3840 -320x = 850
⇔-320x =850-3840
⇔-320 x = -2990

⇔x = 9.34 inches
The new height of the water is = 9.34 inches (approx)
