Answer:

3 cm

Step-by-step explanation:

First, find the volume of the cone.

V = $\frac{1}{3}$ $\pi$ r²h

V = $\frac{1}{3}$ (3.14)(9)(12)

V = 113.04

This means the sphere is also 113.04

Use the formula V = $\frac{4}{3}$ $\pi$ r³

113.04 = $\frac{4}{3}$ (3.14)r³

113.04 = 4.19r³

26.98 = r³

3 ≈ r

Consider the regular octagon below with a center at the organ and a vertex at 4,0

Elan Coil [88]

Reflection on y=0

Step-by-step explanation:

The property to note when a point is reflected on the line y=0 is that the object figure will be congruent to the image figure.Here the distance of the object from the axis of reflection will equal that distance of image from the axis of reflection.In this case, the object point (0,-4) will reflect at (0,-4). The same will occur for object point (0,4) which will reflect at (0,-4). Doing the same for all the points, the image formed will be carried onto the polygon itself.
