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)

Answer:

Volume = 200.96 cubic feet

Step-by-step explanation:

Volume of a cone is given by the formula   [tex]V=\frac{1}{3}\pi r^2 h[/tex]

Where r is the radius and h is the height

Given r = 4 and height is 3 times that. So height is 4*3 = 12

Plugging these into the formula we get:

Volume of Cone =  [tex]\frac{1}{3}\pi (4)^2 (12)\\=\frac{1}{3}(3.14)(16)(12)\\=200.96[/tex]

Thus, Volume = 200.96 cubic feet
