To find the total volume of ice cream in and on top of the cone, we need to calculate the volume of the cone and then add the volume of the hemisphere on top.
**Step 1: Volume of the hemisphere**
The volume \( V \) of a hemisphere can be calculated using the formula:
\[
V = \frac{2}{3} \pi r^3
\]
We know the volume of the hemisphere is given as \( 4 \, \text{in}^3 \). We can set up the equation:
\[
\frac{2}{3} \pi r^3 = 4
\]
To solve for \( r^3 \), we rearrange the equation:
\[
r^3 = \frac{4 \cdot 3}{2\pi} = \frac{12}{2\pi} = \frac{6}{\pi}
\]
Now, we calculate \( r \):
\[
r = \left( \frac{6}{\pi} \right)^{1/3}
\]
**Step 2: Diameter and height of the cone**
According to the problem, the diameter of the cone is equal to its height. If we denote the height of the cone as \( h \) and the radius as \( r_c \), we have:
\[
d = 2r_c = h
\]
From this, we can express the radius \( r_c \) in terms of height \( h \):
\[
r_c = \frac{h}{2}
\]
**Step 3: Volume of the cone**
The volume \( V_cone \) of a cone is given by:
\[
V_{cone} = \frac{1}{3} \pi r_c^2 h
\]
Substituting \( r_c = \frac{h}{2} \):
\[
V_{cone} = \frac{1}{3} \pi \left( \frac{h}{2} \right)^2 h
\]
This simplifies to:
\[
V_{cone} = \frac{1}{3} \pi \left( \frac{h^2}{4} \right) h = \frac{1}{12} \pi h^3
\]
**Step 4: Relating \( h \) to \( r \)**
The hemisphere is mounted on top of the cone, whose dimensions are related through \( h \). Since we need to express \( h \) in terms of \( r \), we know from the earlier hemisphere equation that:
\[
r = \left( \frac{6}{\pi} \right)^{1/3}
\]
To find \( h \), we must express \( h \) in terms of \( r \) from the cone's dimensions. If we take the relationship of the cone's height and diameter:
\[
h = 2r_c = 2\left(\frac{h}{2}\right) \rightarrow h = h
\]
Thus, we directly set the equations for finding the relationship between the hemisphere's volume and the cone’s volume through \( h \).
To summarize, we need to add the two volumes:
1. **Volume of the hemisphere** which is given as \( 4 \).
2. **Volume of the cone** which needs \( h \).
Next, we realize from geometrical properties of \( r\):
Given \( r = \left( \frac{6}{\pi} \right)^{1/3} \rightarrow h = 2r \text{ because diameter = height}; \text{ thus, } r = \sqrt[3]{\frac{3V_{cone}}{ \pi }} (from the cone's volume rearranging).
**Total volume**:
So, assuming consistent geometric placement of each, we add:
\[
V_{total} = V_{cone} + V_{hemisphere}
= \frac{1}{12} \pi h^3 + 4
\]
Once \( h \) and its related hemisphere volume are discerned geometrically or approximated, calculate \( V_{total} \) appropriately.
As you're working through \( h \) and \( r_c = \frac{h}{2} \), having clarity on \( all dimensions/h values directly from volumetric formulas is key in solving this tiered volume comparison.
The culminating confirmed and sealed volume, combined, thus computes leads us to finalize this inquiry and help you finalize needing actual numeric estimates for height to see complete assessment through numerical tabled analysis rather alongside.

To find the total volume of ice cream in and on top of a cone, we need to calculate both the volume of a hemisphere on top and the volume of the cone itself.
1. **Volume of the Hemisphere**:
- The volume \( V \) of the hemisphere is given as \( 4 \text{ in}^3 \).
- Using the formula \( V = \frac{2}{3} \pi r^3 \), we have:
\[
\frac{2}{3} \pi r^3 = 4
\]
- Solving for \( r^3 \), we find:
\[
r^3 = \frac{6}{\pi} \quad \Rightarrow \quad r = \left( \frac{6}{\pi} \right)^{1/3}
\]
2. **Volume of the Cone**:
- The cone's diameter equals its height, expressed as \( h = 2r_c \) (where \( r_c \) is the radius of the cone).
- The volume of the cone is given by:
\[
V_{cone} = \frac{1}{3} \pi r_c^2 h
\]
- Plugging in \( r_c = \frac{h}{2} \) gives:
\[
V_{cone} = \frac{1}{12} \pi h^3
\]
3. **Calculating Total Volume**:
- The total volume of ice cream is:
\[
V_{total} = V_{cone} + V_{hemisphere} = \frac{1}{12} \pi h^3 + 4
\]
- To evaluate \( h \) in terms of \( r \) or vice versa would be necessary but noting the relationship should facilitate calculations appropriately under consistent geometrical proofs.
In conclusion, the total volume of ice cream in and on top of the cone can be found by calculating the volumes separately and then summing them. Further numerical evaluation of \( h \) might be needed to finalize exact values.

To find out the total volume of ice cream in and on top of a cone, we first need to calculate the volume of the hemisphere sitting on top and then the volume of the cone itself. The volume of the hemisphere is given as 4 cubic inches, and we can use the formula for the volume of a hemisphere, which is \( V = \frac{2}{3} \pi r^3 \). After plugging in the given volume, we solve for the radius \( r \), which comes out to be \( r = \left( \frac{6}{\pi} \right)^{1/3} \). For the cone, the diameter is equal to its height, so we can say that \( h = 2r_c \) (where \( r_c \) is the radius of the cone). The formula for the volume of the cone is \( V_{cone} = \frac{1}{3} \pi r_c^2 h \), and when we replace \( r_c \) with \( \frac{h}{2} \), we get \( V_{cone} = \frac{1}{12} \pi h^3 \). Finally, to find the total volume of ice cream, we just add the volume of the cone and the volume of the hemisphere together, giving us \( V_{total} = \frac{1}{12} \pi h^3 + 4 \). We may need to figure out the height \( h \) to get the exact numbers, but this is how we can find the total volume of ice cream in the cone!
