A cone shaped building has a height of 11.4 meters and a base with a diameter of 12 meters . The building will be filled with ro
Vlad1618 [11]

Answer:

The answer to your question is  $ 8591.04

Step-by-step explanation:

Data

height = 11.4 m

diameter = 12 m

cost = $20/ft³

Process

1.- Calculate the volume of the cone

Formula

Volume = 1/3 πr²h

Substitution

Volume = 1/3 (3.14)(12/2)²(11.4)

Simplification

Volume = 1/3(1288.66)

Volume = 429.55 m³

2.- Calculate the cost

                $20 ----------------- 1 m³

                   x   ----------------- 429.55 m³

                   x = (429.55 x 20)/ 1

                   x = $ 8591.04

What is the volume in cubic units of a cylinder diameter 6 and height 4
katrin2010 [14]

Hey there!

The formula for the volume of a cylinder is \pi r^{2} h, which is essentially the base multiplied by the height.

If our diameter is six, then our radius is three, so we can solve for our base below. We will use 3.14 for pi.

3^{2}(3.14)=28.26

Now, we multiply this by our height of four.

28.26(4)=113.04

Therefore, our volume is 113.04 cubic units.

I hope this helps!

Find the distance between the two points in simplest radical form.<br> (7,-1) and (9,-9)
storchak [24]

Answer:

\sqrt{68}

Step-by-step explanation:

(7 , -1) = (x1 , y1)

(9 , -9) = (x2 , y2)

distance formula = \sqrt{(x2 - x1)^2 + (y2 - y1)^2}

=\sqrt{(9 - 7)^2 + (-9 - (-1))^2}

=\sqrt{2^2 + (-9 + 1)^2}

=\sqrt{4 + (-8)^2}

=\sqrt{4 + 64}

=\sqrt{68}
