Answer:
39 pi cubic inches
Step-by-step explanation:
The volume of a cone is (1/3)(area of the base)(height).

Find the area of the circular base. The circumference of a circle is
, so

Now that you know the radius of the circular base, you can find its area:

The height of the cone is 13. Time to use the volume formula.

Answer:
ok

Step-by-step explanation:
Answer:
14m^2
Step-by-step explanation:
Area of a triangle is - 1/2 base times hight
two triangels find the srea of both and add them
4x4x1/2 = 16x1/2 = 8m
3x4x1/2 = 12x1/2 = 6m
6m + 8m = 14m
To answer this, just set each factor = to 0 and solve for x:
x=0
x=3
x=-9
x=7
so the zeros of the function are {-9, 0, 3, 7}.
