**Reiny**, Sunday, January 27, 2013 at 11:07pmYour formula is not correct, it should be

Sn = n(a + l)/2 or (n/2)(first + last)

your equation makes no sense

**Katie**, Monday, January 28, 2013 at 9:27amV= 4/322/7r^ 3

v= 4/3 *22/7*(6 1/4 in)^3

v=3/4 * 22/7 * 15625/64

v= 1023.065476 how to change to a mix-number?
