Answer:
The volume of the cone is 3π≈9.42.
The surface area of the cone is 9π≈28.27.
Step-by-step explanation:
If we make a section of the sphere and the cone, we have a equilateral triangle inscribed in a circle (see picture attached).
We only know the numerical value of the radius R, that is 2 m.
From the picture, we have
The radius of the base of the cone is
The height of the cone can be calculated as:
The volume of the cone can be calculated as:
The surface area of the cone is:
