Find the volume of the cone of the height is 18 feet and the radius is 30 feet

=16956 ft^3

Step-by-step explanation:

The volume of a cone is given by

V = 1/3 pi r^2 h

We are given the height =18 and radius = 30

V = 1/3 (3.14) (30)^2 (18)

   = 1/3 (3.14) 900 * 18

    =16956 ft^3

answer: what

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
