r = radius of cone h = height of cone Volume of cone = ( 1 / 3 ) * ( 3.14 ) * ( r * r ) * ( h ) we get radius of cone from the derivation is root ( 2 ) times multiple of R we get height of cone from the derivation is 4 times multiple of R
let V = ( ( 1 / 3.0 ) * ( 3.14 ) * ( 2 * ( R * R ) ) * ( 4 * R ) ) ; return V ; }
