Debbie buys a tree for the holidays. she would like to determine the amount of space it will take up in her living room. the tree is cone shaped and has a radius of 4 feet. find the volume of the tree if it is in the shape of a cone and its height is three times its radius. the radius of a cone whose height is is equal to three times its radius is given as: r=root(frac(3v,3π),3) (use π=3.14)

Volume of cone = 200.96 square feet              

Step-by-step explanation:

We are given the following information in the question:

The tree is cone shaped and has a radius of 4 feet.

r = 4 feet

The height of the tree is three times its radius.

Volume of tree =

Putting all the values, we get,

Radius of cone whose height is is equal to three times its radius is given as:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
