Aimee packs ice cream into an ice cream cone. She then puts a perfect hemisphere of ice cream on top of the cone that has a volume of 4 in.^3 The diameter of the ice cream cone is equal to its height. What is the total volume of ice cream in and on top of the cone? Use the relationship between formulas for the volumes of cones and spheres to help solve this problem. Show your work and explain your reasoning.

Please answer correctly.

To solve this problem, we can use the formulas for the volume of a cone and the volume of a sphere.

The volume of a cone is given by the formula V_cone = (1/3) * π * r^2 * h, where r is the radius of the base and h is the height of the cone.

The volume of a sphere is given by the formula V_sphere = (4/3) * π * r^3, where r is the radius of the sphere.

In this problem, the diameter of the ice cream cone is equal to its height. Let's call this value d.

Since the diameter is equal to twice the radius, we have r = d/2.

The volume of the hemisphere on top of the cone is given as 4 in^3. Since the hemisphere is half of a sphere, the volume of the whole sphere is 2 * 4 = 8 in^3.

Using the volume formula for the sphere, we can solve for the radius:
8 = (4/3) * π * r^3
r^3 = 8 / ((4/3) * π)
r^3 = 6 / π
r ≈ 1.18097 in

Since the diameter of the cone is equal to its height, the radius is d/2 ≈ 1.18097 in.

Now we can substitute the values into the formula for the volume of the cone:
V_cone = (1/3) * π * (1.18097)^2 * 1.18097
V_cone ≈ 1.9635 in^3

Therefore, the total volume of ice cream in and on top of the cone is 1.9635 + 8 = 9.9635 in^3.
