Answer:

$33.60

Step-by-step explanation:

20% discount on an original price of $40 = $8

5% of $32 = $1.60

32 + 1.60 = $33.60

A cylinder has a helght of 16 cm and a radius of 5 cm. A cone has a helght of 12 cm and a radius of 4 cm. If the cone is placed

erma4kov [3.2K]

Answer:

1055.04 cm³

Step-by-step explanation:

Given that,

Height of a cylinder, h = 16 cm

Radius of the cylinder, r = 5 cm

The height of a cone, h' = 12 cm

The radius of a cone, r' = 4 cm

The volume of the cylinder will be :

$V=\pi r^2 h\\\\=3.14\times 5^2\times 16\\\\=1256\ cm^3$

The volume of a cone is given by :

$V'=\dfrac{1}{3}\pi r^2 h\\\\=\dfrac{1}{3}\times 3.14\times (4)^2\times 12\\\\=200.96\ cm^3$

Volume of the air surrounding the cone Inside the cylinder = 1256 - 200.96 = 1055.04 cm³

Hence, the required answer is equal to 1055.04 cm³.

Find the coordinates of the vertices of the triangle if it’s rotated 270° counterclockwise.

Scilla [17]

If these coordinates are rotated 270° counterclockwise, the resulting coordinates will be;

<em>X' = (3, -1)</em>

<em>Y' = (2, -2)</em>

<em>Z' = (-1, -3)</em>

<h3>Rotation of coordinates</h3>

If the coordinates (x, y) is rotated 270° counterclockwise, the resulting coordinate point will be;

(x, y) - > (y, -x)

From the given triangles, the coordinate points are expressed as

<em>X = (1, 3)</em>

<em>Y = (2, 2)</em>

<em>Z = (3, -1)</em>

If these coordinates are rotated 270° counterclockwise, the resulting coordinates will be;

<em>X' = (3, -1)</em>

<em>Y' = (2, -2)</em>

<em>Z' = (-1, -3)</em>
