To first find the volume of the sphere, you need to first find the radius. To find this, you take the circumference of 29.5 inches and divide by pi to get the diameter.

Then divide the diameter by 2 to get the radius.

So we get a radius of about 4.70.

Then we use the formula for the volume of a sphere which is

Substituting in R for 4.69........, we get

Rounded to the nearest inch, we get 434 inches cubed.
