Simplify.

WITCHER [35]

Answer:

20x + 22

Step-by-step explanation:

34- 4x + 12x -12 +12x

step 1: 34 - 12 = 22

now you have left: -4x + 12x +12x

step 2: 12x +12x = 24x

step 3: 24x - 4x = 20x

Now you will combine the two answers you got: 20x +22

Hope this helps :)

A paper container in the shape of a right circular cone has a radius of 3 inches and a height of 8 inches. Determine and state t

Scrat [10]

Given:

Radius of the cone = 3 inches

Height of the cone = 8 inches

To find:

The volume of the cone, in terms of π.

Solution:

We know that, the volume of a cone is:

$V=\dfrac{1}{3}\pi r^2h$

Putting $r=3,h=8$ , we get

$V=\dfrac{1}{3}\pi (3)^2(8)$

$V=\dfrac{1}{3}\pi (9)(8)$

$V=\dfrac{72}{3}\pi$

$V=24\pi$

Therefore, the volume of the cone is $24\pi$ .
