You need to find the slope of the line too. they use m to represent slope.
m   = \frac{(y2 - y1)}{x2 - x1} =  \frac{ - 2 - 2}{ - 2 - 2}  =   \frac{ - 4}{ - 4}  =  \frac{1}{1}
point slope equation is y - y1 = m(x -x1)
they said to use point (-2, -2)
y -(-2) = 1(x -(-2))
y +2 = 1(x +2)

The volume of the cone shown is 5 cubic inches. What is the height of a cone with the same base diameter but a volume of 10 cubi
MaRussiya [10]

Answer:

The height of the second cone is 2 <em>h</em>₁.

Step-by-step explanation:

The volume of a cone is:

V=\pi\ r^{2}\frac{h}{3}

The volume of the first cone is, <em>V</em>₁ = 5 in³.

The volume of the second cone is, <em>V</em>₂ = 10 in³.

The two cones have the same base diameters.

This implies that the two radii are same, i.e. <em>r</em>₁ = <em>r</em>₂.

Compute the height of the second cone as follows:

   r_{1}=r_{2}

\frac{3\cdot V_{1}}{\pi\ h_{1}}=\frac{3\cdot V_{2}}{\pi\ h_{2}}

  \frac{V_{1}}{h_{1}}=\frac{V_{2}}{ h_{2}}

  \frac{5}{h_{1}}=\frac{10}{h_{2}}

  h_{2}=2\ h_{1}

Thus, the height of the second cone is 2 <em>h</em>₁.
