What's The Volume Of The Cone

Answers

Answer 1
Given:-

[tex] \bullet [/tex] Radius (r) of the cone is 3 ft.

[tex] \bullet [/tex] Height (h) of the cone is 9 ft.

To Find:-

The volume of the cone.

Solution:-

We know,

Formula of Volume of cone is [tex] \frac{1}{3} [/tex]πr²h

So, Volume of the cone = [tex] \frac{1}{3} [/tex] × [tex] \frac{22}{7} [/tex] × (3)² × 9

Volume of the cone = [tex] \frac{1}{3} [/tex] × [tex] \frac{22}{7} [/tex] × 3 × 3 × 9

Volume of the cone = [tex] \frac{22 \: × \: 3 \: × \: 3 \: × \: 9}{3 \: × \: 7} [/tex]

Volume of the cone = [tex] \frac{1782}{21} [/tex]

Volume of the cone = 84.86 cubic ft.

The volume of the cone is 84.86 cubic ft. [Answer]

Work out the point of intersection of the lines
2x + 3y = 11 and 2y = 13 – 3x

Answers

Answer:

x = 3.4

y = 1.4

Step-by-step explanation:

2x + 3y = 11

2y = 13 – 3x, then y = (13 - 3x)/2

substitute for y:

2x + 3((13 - 3x)/2) = 11

reduce:

2x + (39 - 9x)/2 = 11

reduce:

2x + 19.5 - 4.5x = 11

subtract 19.5 from both sides of the equation and combine for x:

-2.5x = -8.5

divide both sides by -2.5:

x = 3.4

y = (13 - 3(3.4))/2 = (13 - 10.2)2 = 1.4

Explain

.

If median are getting from " ( a + b ) ÷ 2 " . So :

.

Find b :

.

(a + b) ÷ 2 = Median

(17 + b) ÷ 2 = 18

17 + b = 18 × 2

17 + b = 36

b = 36 - 17

b = 19

.

In conclusion, the value of b is 19

[tex]161 + a = 17 \times 10[/tex]

[tex]161 + a = 170[/tex]

[tex]a = 170 - 161[/tex]

[tex]a = 9[/tex]

In conclusion, the value of a is 9

Robert is baking desserts for a picnic. He needs to make at least 20 servings of dessert for the
event. For every batch of brownies he bakes, he will get 8 servings, and every pie will
yield 14 servings.

Answers

Answer:

x*8 + y*14 ≥ 20

Step-by-step explanation:

We know that:

A batch of brownies makes 8 servings.

A pie makes 14 servings.

He wants to make, at least, 20 servings.

Then if he makes x batches of brownies, he will get x times 8 servings.

If he makes y pies, he will get y times 14 servings.

Adding that, he will get a total of:

x*8 + y*14 servings

And because he wants to make at least 20 servings (he can make 20 or more)

The inequality will be:

x*8 + y*14 ≥ 20

Where the "≥" symbol means that the expression at the left is greater than or equal to the expression of the right
