Find the volume of the cone shown as a decimal rounded to the tenth. 22m 12m

Mathematics
1 answer:
Luda [366]2 years ago
3 0

Answer:

b

Step-by-step explanation:

the volume (V) of a cone is calculated as

V = \frac{1}{3}πr²h ( r is the radius , h is the height )

here diameter = 12 , so r = 12 ÷ 2 = 6 and h = 22 , then

V = \frac{1}{3}π × 6² × 22

   = \frac{1}{3}π × 36 × 22

    = \frac{1}{3}π × 792 ( cancel 3 and 792 by 3 )

    = π × 264

    ≈ 829.4 m³ ( to the nearest tenth )

Find the distance when y2=9, y1=13, x2=4, and x1=0.
Ket [755]

Answer:

Tthe distance between \left(x_1,\:y_1\right)=\left(0,\:13\right) and \left(x_2,\:y_2\right)=\left(4,\:9\right) will be:

  • \mathrm{Distance\:between\:}\left(0,\:13\right)\mathrm{\:and\:}\left(4,\:9\right):\quad 4\sqrt{2}

Step-by-step explanation:

Given the points

  • \left(x_1,\:y_1\right)=\left(0,\:13\right)
  • \left(x_2,\:y_2\right)=\left(4,\:9\right)

\mathrm{Compute\:the\:distance\:between\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}

\mathrm{The\:distance\:between\:}\left(0,\:13\right)\mathrm{\:and\:}\left(4,\:9\right)\mathrm{\:is\:}

=\sqrt{\left(4-0\right)^2+\left(9-13\right)^2}

=\sqrt{4^2+4^2}

=\sqrt{4^2\cdot \:2}

\mathrm{Apply\:radical\:rule\:}\sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b},\:\quad \mathrm{\:assuming\:}a\ge 0,\:b\ge 0

=\sqrt{2}\sqrt{4^2}

\mathrm{Apply\:radical\:rule\:}\sqrt[n]{a^n}=a,\:\quad \mathrm{\:assuming\:}a\ge 0

=4\sqrt{2}

Therefore, the distance between \left(x_1,\:y_1\right)=\left(0,\:13\right) and \left(x_2,\:y_2\right)=\left(4,\:9\right) will be:

  • \mathrm{Distance\:between\:}\left(0,\:13\right)\mathrm{\:and\:}\left(4,\:9\right):\quad 4\sqrt{2}

If y = 3 when X = -9 find X when y =5
kogti [31]
We don't have enough information to answer that question.

You haven't told us anything about how 'y' depends on 'x',
or how 'y' reacts to a change in 'x'.

If we think about it in terms of a graph, you've given us one point
on the graph . . . the point  (-9, 3).  In order to answer the question,
we need to know something about the line that goes through the
point.  But you haven't told us anything about that, and there are
an infinite number of different lines that can go through one point.

Can someone help with numbers 15 and 16
vichka [17]
15.

I had x before the movie.

x - 13.50 = 26.50

Add 13.50 to both sides of the equation:

x = 40

I had $40 before the movie.

16.

The original balance was x.

x - 161.15 = 423.28

Add 161.15 to both sides:

x = 584.43

The previous balance was $584.43

Question 3 help me please
crimeas [40]

Answer:

3x+(4x-1)+90°=180°{sum of angles in a triangle}

3x+4x-1+90°=180°

7x+89°=180°

7x=180°-89°

7x=91°

divide both sides by 7

x=13
