Answer:

351π ft³

Step-by-step explanation:

Volume of a Cone is: $\frac{1}{3} \pi r^2h$

Where r is the radius and h is the height.

The cone's radius is 9 while the height is 13.

$\frac{1}{3}( \pi* 9^2*13)\\9^2 = 81\\81 * 13 = 1053\\\rightarrow\frac{1}{3} 1053\pi \\1053/3 = 351\\\boxed {V=351\pi}$

The volume of the cone in exact form is 351π ft³.

Option A).

(0,2) , (2,3) , (0,-2) , (4,1)

here 0 has two image 2 and -2.

So, this is not function.

Option B).

(1,2) , (1,-2) , (3,2) , (3,4)

here 1 has two image 2 and -2.

So, this is not function.

Option C).

(1,6) , (2,7) , (4,9) , (0,5)

Here every element has only one image.

So, this is a function.

Option D).

(2,4) , (0,2) , (2,-4) , (5,3)

here 2 has two image 4 and -4.
