Vinil7 [7]

Answer:

The axis of symmetry is x = 6

Step-by-step explanation:

To find this, first find the two x-intercept values and then take the average. This will always be the line of symmetry.

x + 9 = 0

x = -9

x - 21 = 0

x = 21

Now take the average of these two numbers.

Hello!

The equation to find the volume of a cone is

$\pi r^{2} \frac{h}{3}$

r is radius
h is height

Put in the values we know

$3.14 * 9^{2} * \frac{4}{3}$

Square the number

$3.14 * 81 * \frac{4}{3}$

multiply 81 by 3.14

$254.34 * \frac{4}{3}$

Multiply

339.12

The answer is 339.1 cubic inches

Hope this helps!
