Answer:

x = 4

Step-by-step explanation:

-5w + 7 - w + 4 = -13

-5w - w + 7 + 4 = -13

-6x + 11 = -13

-6x = -13 - 11

-6x = -24

-6x/-6 = -24/-6

x = 4

A cone has a diameter of 3 inches. The cone holds 12 cubic inches of water.
dmitriy555 [2]

Answer:

The  height of the cone is 5.09 inches

Step-by-step explanation:

Given:

The volume of the cone  =  12 cubic inches

The diameter of the cone  = 3 inches

To Find :

The height of the cone  =  ?

Solution:

We know that the volume of the cone is

Volume  = \pi r^2\frac{h}{3}

where

r is the radius of the cone

h is the  height of the cone

Now substituting the given values

12 = \pi (1.5)^2  \frac{ h }{3}

\frac{12}{\pi 2.25}  = \frac{h}{3}

h = \frac{12}{ 2.25 \pi} \times 3

h = \frac{ 12}{7.065} \times 3

h = 1.698 \times 3

h =  5.09  inches
