A pastry bag is a tool used to decorate cakes and cupcakes. Pastry bags take the form of a
truncated cone when filled with icing. What is
the volume, to the nearest thousandth, of a
pastry bag with a height of 27 inches, large
radius of 13 inches, and small radius of 7 inches?

i'm not sure i quite understand, could you provide more information?

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.

answer is : muchas/tipicas

have a nice day!
