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

Please guys i really need your help and please explain how you got it please
lina2011 [118]
The answer would be C because in order to find the area of a figure, you would need to multiply its height by its width. finding the area of a figure is the same as finding how many units are in a figure. because this is a square and all the sides are equal, by counting the total number of units, you can find the area.

Consecutive integers are 1,2,3,4 and so on. Consecutive even integers are 2,4,6,8 and so on. The sum of an integer and twice the
antiseptic1488 [7]

the numbers are x=58 & x+2=60 , i.e. 58 and 60 .

<u>Step-by-step explanation:</u>

Here we have , Consecutive integers are 1,2,3,4 and so on. Consecutive even integers are 2,4,6,8 and so on. The sum of an integer and twice the next consecutive even integer is 178. We need to Write and solve an equation to find the two integers. Let's find out:

Let the integer be x  , and the next consecutive even integer be  x+2 .Now , According to question , The sum of an integer and twice the next consecutive even integer is 178 i.e.

⇒ x + 2(x+2)=178

⇒ x + 2x+4=178

⇒ 3x+4=178

⇒ 3x=174

⇒ \frac{3x}{3}=\frac{174}{3}

⇒ x=58

Therefore , the numbers are x=58 & x+2=60 , i.e. 58 and 60 .
