The cirucumference of a ballon is 75 inches and the diameter is 12 inches what is the volume?
Science  Ms. Sue, Saturday, February 18, 2012 at 9:54pm Thank you.
volume = 4/3 ð r3
V = (4/3) * 3.14 * 6^3
V = (4/3) * 3.14 * 216
V = (4/3) * 678.24
V = ?
I am still confuse how I figure out the answer? What is the process?

If then circumference is 75 inches and the ballon is spherical, then the diameter must be 75/pi = 23.87 inches.
In that case, the RADIUS, not the diameter, would be not quite 12 inches.
The data you have been given is incosistent. What is the shape of your balloon?
