Big cone radius = 8m. Little cone slant height = 6m. Little cone radius = 4m \(\text{curved surface area of cone} = \pi rl\) The curved surface area of the frustrum can be found using: ...

The volume of a cylinder is π × r² × l (r is the radius of the circle and l is the length of the cylinder). To calculate the volume we multiply these values together. The answer will be ...
