The first question is clearly incomplete. The model is not presented so we cannot estimate the volume of the flask but if it was given, the volume is equal to the volume of the cylinder plus the sphere. The cylinder volume is V = pi(r^2)h.
To find the volume of the sphere we use the given equation <span>4/3πr^3. The radius is 4.5/2. The volume is 47.71 cubic inches. </span>
