The volume of a right circular cone that has a height of 13 m and a base with a diameter of 3.4 m. Round your answer to the near

Mamont248 [21]

Answer:

The volume of right circular cone having height = $13 \ m$ and Diameter = $3.4 \ m$ is $39.4\ cubic\ meter$ .

Step-by-step explanation:

Diagram of the given scenario is shown below.

Given that

Height of a right circular cone is $13 \ m$ .

Diameter of the right circular cone is $3.4 \ m$ .

To find: The volume of a right circular cone.

So, From the question,

$Height = \ 13 \ m\\diameter = 3.4\ m$

$Radius = \frac{diameter}{2}= \frac{3.4}{2}$

⇒ $Radius = 1.7\ m$

Now

Volume of right circular cone = $\frac{1}{3}\pi r^{2}h$

$=\frac{1}{3}\times\frac{22}{7} \times (1.7)^{2}\times 13$

= $\frac{826.54}{21}$

$= 39.4\ cubic\ meter$ .

Therefore,

The volume of right circular cone having height = $13 \ m$ and Diameter = $3.4 \ m$ is $39.4\ cubic\ meter$ .

Find the slope that passes through (2,-4) and (5,2)

yanalaym [24]

Hi there! :)

Step-by-step explanation:

$SLOPE=\frac{Y_2-Y_1}{X_2-X_1}=\frac{RISE}{RUN}$

$\frac{2-(-4)}{5-2}=\frac{6}{3}=2$

<u><em>Therefore, the slope is 2.</em></u>

<u><em>Final answer is 2.</em></u>

<u><em>*The answer must have a positive sign.*</em></u>

I hope this helps you!

Have a nice day! :)

A. A 5in radius ball is in a

abruzzese [7]

Answer:

52.33%

Step-by-step explanation:

Since, all six sides of the box are touching the ball.

So, all the three dimensions of the box are equal.

Hence, it is a cubical box.

Side length of the box (l)

= diameter of the ball

= 2*radius of the ball

= 2*5

= 10 In.

$V_{ball} = \frac{4}{3} \pi r^3$

$V_{ball} = \frac{4}{3} \times 3.14(5)^3$

$V_{ball} = \frac{4}{3} \times 3.14\times 125$

$V_{ball} = \frac{1,570}{3}\: In^3$

$V_{box} =l^3$

$V_{box} =(10)^3$

$V_{box} =1000\: In^3$

Percentage of the space in the box occupied by the ball

$= \frac{V_{ball}}{V_{box} } \times 100$

$= \frac{\frac{1,570}{3}}{1000} \times 100$

$= \frac{1570}{3000} \times 100$

$= \frac{157}{3}$

$= 52.33\%$
