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 the formulas for the volumes of cones and spheres to help solve this problem. Show your work and explain your reasoning, and simplify your answer down to three sentences.

The volume of a cone is given by the formula V = (1/3)πr^2h, where r is the radius and h is the height. The volume of a hemisphere is given by the formula V = (2/3)πr^3. Since the diameter of the cone is equal to its height, we can set the radius of the cone equal to half its height. Let's call that value x. We can then substitute this value into the formulas for the volumes of the cone and hemisphere to find the total volume of ice cream.

The volume of the cone is V_cone = (1/3)π(x/2)^2(x) = (1/12)πx^3

The volume of the hemisphere is V_hemisphere = (2/3)π(x/2)^3 = (1/12)πx^3

The total volume of ice cream is V_total = V_cone + V_hemisphere = (1/12)πx^3 + (1/12)πx^3 = (2/12)πx^3 = (1/6)πx^3

Given that the volume of the hemisphere is 4 in^3, we can set up the equation (1/12)πx^3 = 4 and solve for x.

(1/12)πx^3 = 4
πx^3 = 48
x^3 = 48/π
x = (48/π)^(1/3)

Substituting this value of x back into the equation for the total volume, we have:

V_total = (1/6)π[(48/π)^(1/3)]^3
= (1/6)π[48^(1/3)]
= (1/6)π(3.634)
≈ 1.912 in^3

The total volume of ice cream in and on top of the cone is approximately 1.912 in^3.
