Answer:

A. The volumes are the same, based on Cavalieri's principle.

Step-by-step explanation:

Cavalieri's principle tells us the volumes of solids will be identical if their cross sectional areas are identical at every height.

<h3>Application</h3>

A right cylinder and an oblique cylinder of the same height and radius will both have circular cross sections of the given radius at any height. Since the radius is the same, the area of the circle is the same. Hence the requirements of Cavalieri's principle are met, and the cylinders have the same volume.

and United States Lowe's sells particular carpet for $4.88 per square foot in the United Kingdom carpetright sells assembler car

Alisiya [41]

The carpet of United Kingdom carpet-right is cheaper by 3.33 dollars/ft²

<u><em>Explanation</em></u>

Price of the carpet in United States Lowe's is 4.88 dollars/ft²

Price of the carpet in United Kingdom carpet-right is 12.99 pound sterling/m²

1 pound sterling = 1.28 US dollars and 1 meter = 3.28 ft . So....

12.99 pound sterling/ m²

$=\frac{(12.99) pound sterling}{(1 meter)^2}\\ \\ = \frac{(12.99*1.28)dollars}{(3.28 ft)^2} =\frac{16.6272 dollar}{10.7584 ft^2}= 1.55 dollar/ft^2$

<u>As the unit price of the carpet per square feet in United Kingdom carpet-right is less than United States Lowe's</u>, so the carpet of United Kingdom carpet-right is cheaper by $(4.88-1.55)dollar/ft^2 = 3.33 dollar/ft^2$
