The volume of the container is 5969 cm³. The correct option is D. 5,969 cm³

<h3>Calculating Volume </h3>

From the question, we are to determine the volume of the container

Volume of the container = Volume of the cone - Volume of the small cone

The volume of a cone is given by the formula,

V = 1/3πr²h

Where V is the volume

r is the radius

and h is the height

From the given information,

For the small cone,

Diameter = 10 cm

∴ Radius, r = 10cm/ 2 = 5 cm

h = 6 cm

For the big cone

diameter = diameter of the container = 30 cm

∴ Radius = 30cm/ 2

Radius = 15cm

h = height of small cone + height of container

h = 6 cm + 20 cm

h = 26 cm

Putting the parameters into

Volume of the container = Volume of the cone - Volume of the small cone

We get,

Volume of the container = 1/3π × 15² ×26 - 1/3π × 5² × 6

Volume of the container = 1/3π (15² ×26 -  5² × 6)

Volume of the container = 1/3π (5850 -  150)

Volume of the container = 1/3π (5700)

Volume of the container = 1/3 × π × 5700

Volume of the container = 5969.026 cm³

Volume of the container ≈ 5969 cm³

Hence, the volume of the container is 5969 cm³. The correct option is D. 5,969 cm³

Answer:

x = 60

y = 200

Step-by-step explanations:

Selling price:

Price of program = $0.5

Price of music = $5

Cost of production :

Program = $0.15 per program

CD = $1.75 per CD

Total Revenue = $400

Total Profit = $265

Let

Number of CD's = x

Number of program's = y

(0.5y + 5x) = 400

0.5y = 400 - 5x

y = (400 - 5x) / 0.5

y = 800 - 10x (1(

Cost of production:

1.75x + 0.15y

Profit = Total Revenue - Total cost of production

5x + 0.5y - 1.75x + 0.15y = 265

3.25x + 0.35y = 265 (2)

Put y = 800 - 10x in (2)

3.25x + 0.35y = 265

3.25x + 0.35(800 - 10x) = 265

3.25x + 280 - 3.5x = 265

-0.25x = - 15

Divide both sides by -0.25

x = -15/ -0.25

x = 60

y = 800 - 10x

= 800 - 10(60)

= 800 - 600

= 200

y = 200

Find the length of the leg x. enter the exact value, not a decimal approximation x1210x=
zzz [600]

We can solve for the value of x using pythagorean theorem

c^2=a^2+b^2

where c is the hypotenuse ( in this case is 15) and a, b are the other legs of the triangle ( in this case is 8 and x).

Let's substitute the given values to the formula

\begin{gathered} c^2=a^2+b^2 \\ 15^2=8^2+x^2 \\ 225=64+x^2 \\ x^2=225-64 \\ x^2=161 \\ x=12.69 \end{gathered}

Now please follow this solution to solve for x in:
