If you make a glass in the shape of a right circular cone (think martini glass) how wide would the glass be if it is 4 inches tall and again holds 12 oz.
Does not specify what the 12 oz are

geometry 
bobpursley,
Figure 12 fluid ouncces, which is 12*1.804 in^3
Volumecone= 1/3 areabase*height
12*1.803 in^3=1/3 PI *(diameter/2)^2*4
solve all this for diameter
