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?

• Science -

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?
