Answer:
The volume of the cone is 12936 cubic mm.
Step-by-step explanation:
Given
Circumference of base = 132 mm
Height of the cone = 28 mm
Solution
Formula of circumference =
= 132 mm

Now volume of cone = 
on substituting the value of r and h we get ;

thus volume of cone is 12936 cubic mm.
Use the formula for area of a circle,

and they give an approximation so use that for pi
(x+6)(x-6) is the corrector factoring if what you meant was x^2-36
