Answer:
The answer is "138.10"
Step-by-step explanation:
Let r also be cone base radius and h = the cone height.
The radius for the original circle was on either side of the cone plied together = 7.
The hypotenuse is 7, as well as a right triangle, is formed. So:
Calculating the volume of the cone:
Setting the derivative to zero and solving for h^2:
Calculating the maximum volume:
