Answer:

Volume of Cone =

$= \frac{1}{3}\pi (2)^2 (4)\\\\=\frac{1}{3}(3.14)(4)(4)\\\\=\frac{1}{3}\times 3.14\times 16 \\\\=\frac{1}{3}\times50.24\\\\=16.746\\\\\approx16.75 \texttt {ft} ^3$

Thus, Volume = 16.75 cubic feet

Step-by-step explanation:

Volume of a cone is given by the formula

$V=\frac{1}{3}\pi r^2 h$

Where r is the radius and

h is the height

Given radius r = 2 and

height is 2 times that.

So height is 2*2 = 4

Plugging these into the formula we get:

Volume of Cone =

$= \frac{1}{3}\pi (2)^2 (4)\\\\=\frac{1}{3}(3.14)(4)(4)\\\\=\frac{1}{3}\times 3.14\times 16 \\\\=\frac{1}{3}\times50.24\\\\=16.746\\\\\approx16.75 \texttt {ft} ^3$

Thus, Volume = 16.75 cubic feet

Leviafan [203]

Given two points. we can find the equation of a line passing through the points

The formula to be used is:

$\frac{y_2-y_1}{x_2-x_!}=\frac{y-y_1}{x-x_!}$

where

$x_1=3,y_!=-2,x_2=3,y_2=4$ $\frac{4-(-2)}{3-3}=\frac{y-(-2)}{x-3}$

=>

$\frac{6}{0}=\frac{y+2}{x-3}$

The next step is to cross multiply

$6(x-3)=0(y+2)$

=>

$6(x-3)=0$

Divide both sides by 6 and make x the subject

x=3

Which of the following are situations that can be modeled with a quadratic function? Select all that apply.

Lina20 [59]

Answer:

Option 2 and 5 are correct.

Step-by-step explanation:

We need to tell which one of them is quadratic function.

Option 1 is exponential decay so, it is not quadratic.

Option 2 is quadratic because the diver will take the parabolic shape when jumps.

Option 3 is not quadratic.Option 4 is not quadratic it is linear.

Option 4 is again exponential not quadratic.

Option 5 is quadratic because it takes the parabolic shape again.
