Answer:
The Answer is D or V= 2/3(11).
Step-by-step explanation:
If the cylinder and sphere have the same height and radius, the sphere will be 2/3 the volume of the cylinder. Hence, the answer will be D.
Answer:
4(2x-y) (2x+y)
Step-by-step explanation:
The area of the picture is 2y*2y = 4y^2
The area of the picture and the frame is 4x*4x = 16x^2
The area of the frame is The area of the picture and the frame minus The area of the picture
The area of the frame = 16x^2- 4y^2
Factor out a 4
4(4x^2 -y^2)
This is the difference of squares
a^2 – b^2 = (a + b)(a – b)
a^2 = 4x^2 so a=2x
b^2 = y^2 so b=y
4(4x^2 -y^2) = 4(2x-y) (2x+y)

The height of the building is 210 feet.
<u><em>Explanation</em></u>
A 42 feet tall flagpole casts a shadow 9.2 feet long. That means, the ratio of the length of flagpole to the length of its shadow will be:
Now, a building casts a shadow 46 feet long. Suppose the height of the building is feet.
As the <u>ratio will be same for Flagpole and Building at same time</u>, so....
So, the height of the building is 210 feet.
