Tobias is constructing pylons to prevent cars from driving on a bike path. How much concrete, in cubic feet, will Tobias need fo

Naddika [18.5K]

Answer: $\frac{2}{3}\pi \ ft^3$

Step-by-step explanation:

Since you indicate that it is a cone, you need to use the formula for calculate the volume of a cone. This is:

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

Where "r" is the radius and "h" is the height of the cone.

According to the information given in the exercise, the height and the radius of the pylons are the following:

$r=1\ ft\\\\h=2\ ft$

Then, knowing these values, you can substitute them into the formula,as following:

$A_{cone}=\frac{1}{3}\pi (1\ ft)^2(2\ ft)$

Finally, evaluating, you get that the volume of concrete that Tobias will need for each pylon is the one shown below:

$A_{cone}=\frac{1}{3}\pi (2\ ft^3)\\\\A_{cone}=\frac{2}{3}\pi \ ft^3$

Step-by-step explanation:

4(x-7)=2x-6 to get the second problem you distribute the 4 to the 7 and x

4x-28=2x-6 subtract the 2x from 4x

2x-28=-6 then u add the 28 to the negative 6

2x=22 divide

x=11
