Find the volume of a cone with a base radius of 6 cm and a height of 10 cm write in terms of pie
Savatey [412]

Answer:

  • <u>Volume of the cone is 120 π cm³ </u>

Step-by-step explanation:

Given that Base radius of cone is 6 cm and height is 10 cm and we need to find volume of the cone. Volume of cone is given by:

\\ \:  \:    \dashrightarrow \:  \:  \: \underline{\boxed{\pmb{\sf{Volume_{(cone)} = \dfrac{1}{3} \pi r^2 h }}}}  \\ \\

On Substituting the required values, we get:

\\ \:  \: \dashrightarrow \:  \:  \sf \: Volume_{(cone)} =  \frac{1}{3}  \times  \pi \times  {(6)}^{2}  \times 10 \\  \\  \\  \:  \: \dashrightarrow \:  \:  \sf \: Volume_{(cone)} = \frac{1} {\cancel{3}}  \times  \pi \times  \cancel{36} \times 10 \\ \\   \\  \:  \: \dashrightarrow \:  \:  \sf \: Volume_{(cone)} = \pi \times 12 \times 10 \\  \\  \\  \:  \: \dashrightarrow \:  \:  \sf \: \: { \purple{Volume_{(cone)} =120 \pi \: cm^3 }}\\  \\

1. The function, g, is graphed below. EXPLAIN how to find x, if g(x) = -1 in sufficient<br> detail
konstantin123 [22]
<h3>Answer:  x = 1</h3>

=====================================

Explanation:

  • Step 1) Start at -1 on the y axis.
  • Step 2) Draw a horizontal line from -1 until you reach the g(x) curve.
  • Step 3) Mark the point of intersection. Let's call it point A.
  • Step 4) From point A, draw a vertical line until you reach the x axis. You should get to x = 1.

All of this is shown in the diagram below.

Now follow the arrows in reverse. This shows that x = 1 leads to y = g(x) = -1.

Therefore, g(1) = -1 and x = 1 is the solution to g(x) = -1.

Side note: The equation is g(x) = 2x-3. We can replace g(x) with -1 and solve for x to get x = 1.

Which points are on the the graph equation -3x+6y+5=-7
algol [13]
-3x + 6y + 5 = -7
<u>                -5    -5</u>
      -3x + 6y = -12
-3x + 3x + 6y = -12 + 3x
               <u>6y</u> = <u>-12 + 3x</u>
                6           6
                 y = -2 + 1/2x
-3x + 6(-2 + 1/2x) = -12
       -3x - 12 + 3x = -12
         -3 + 3x - 12 = -12
                0x - 12 = -12
                <u>     +12    +12</u>
                       <u>0x</u> = <u>0</u>
                        0     0
                         x = 0
           -3(0) + 6y = -12
                0 + 6y = -12
              <u>+0             +0</u>
                      <u>6y</u> = <u>-12</u>
                       6       6
                        y = -2
                  (x, y) = (0, -2)
