Maximizing the Volume of a Cone

What is the initial problem presented in the video?

• Calculating the perimeter of a circle

• Maximizing the volume of a cone

• Determining the surface area of a sphere

• Finding the area of a triangle

What is the relationship between the hypotenuse and the legs of the triangle in the context of the cone?

• The legs form the base and height of a cylinder

• The legs form the radius and height of the cone

• The hypotenuse is the radius of the cone

• The hypotenuse is the height of the cone

What is the formula used for the volume of a cone in this problem?
