Write a polynomial that has the give numbers as roots-3, 2 +sqrt3

Given roots are (-3)  and ()

is one of the root. So other root is  

So we have three roots -3  , and

Now we write the all the roots in factor form

Now we multiply last two parenthesis

Now combine like terms

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
