Answer:
Step-by-step explanation:
Let 
be the volumes of the smaller and bigger cylinder.
The formula for the volume of a cylinder is given by :
As the two triangles are similar, the cube of their ratio would equal the ratio of their volume i.e.
So, the volume of the smaller cylinder is equal to 
.

Answer:15,400 If u take the equation then the matric rule in the olastrophy and then use clastrophy you get the answer pretty simple
Answer:
D
Step-by-step explanation:
I can explain if you need. Write in comments if you do need.
Using the side of the square find the area:
Area = 30^2 = 900 square feet.
The rectangles area is the same, 900 square feet.
Let the width = X
The length would be 2X + 70
Area = length x width
X * 2x+ 70 = 900
This expands to 2x^2 * 70x = 900
Use the quadratic formula to solve for x:
-70 +/- sqrt(70^2-4*2(-900))/2*2
X = 10
Width = x = 10 feet
Length = 2x + 70 = 90 feet
