3. A prop for the theater club's play is constructed as a cone topped with a half-sphere. What is the volume of the prop? Round
Maksim231197 [3]

Answer:

8138.88 cubic unit.

Step-by-step explanation:

Given that,

Radius, r = 12

Height, h = 18

We need to find the volume of the prop. The volume of a cylinder is given by the formula as follows :

V=\pi r^2 h\\\\V=3.14\times 12^2 \times 18\\\\V=8138.88\

So, the volume of the cylinder is 8138.88 cubic unit.

X / 6 equals -7 solve using the multiplication principle
garik1379 [7]

Answer:

x = -42 is your answer

Step-by-step explanation:

x/6 = -7

Isolate the x. Note the equal sign, what you do to one side, you do to the other.

Multiply 6 to both sides

(x/6)(6) = (-7)(6)

x = (-7)(6)

Simplify. Multiply 6 with -7

x = (-7)(6)

x = -42

What slope does a horizontal line have? Use a number to fill in the blank. HELP FOR TESTTTTTT
Alex73 [517]

Answer:

The slope of a horizontal line is zero

Step-by-step explanation:

All horizontal lines are parallel to the x-axis.

The x-axis has a zero slope.

All parallel lines have the same slope.

Therefore the slope of a horizontal line is zero.

This means there is no rise in y.

So rise over run will become:

0/run=0
