From Geometry we remember that volumes of a cone and a cylinder with the same radius ( $R$ ), measured in feet, and height ( $h$ ), measured in feet, are defined by the following equations:

Cone

$V_{co} = \frac{1}{3}\pi\cdot R^{2}\cdot h$ (1)

Cylinder

$V_{cy} = \pi\cdot R^{2}\cdot h$ (2)

The ratio of the volume of the cylinder to the volume of the cone is:

$\frac{V_{cy}}{V_{co}} = 3$ (3)

If we know that $V_{co} = 100\pi\,ft^{3}$ , then the volume of the cylinder is:

$V_{cy} = 3\cdot V_{co}$

$V_{cy} = 300\pi\,ft^{3}$

The volume of the cylinder is $300\pi$ cubic feet.

What is the percent decrease if the original price is $582 and it went down 30%

Semenov [28]

Answer:

30%

Step-by-step explanation:

What is the percent decrease if the original price is $582 and it went down 30%

or decreased 30%

Check:

582 x 0.70 = 407.4

582-407.4=174.6

174.6/582= 0.3
