Question

Does anyone know 8-10?

Answer 1

#8).
The volume of a cone is      (1/3) (pi) (radius of the round end)² (height)

That's the volume of the ice cream cone alone.

The volume of a sphere is    (4/3) (pi) (radius)³

The glob of ice cream on top is 1/2 of a sphere.
The sphere and the cone in this problem both have the same radius.

#9).
The volume of a cylinder is        (pi) (radius of the round end)² (height)

#10).
Another cylinder !
The volume of a cylinder is        (pi) (radius of the round end)² (height)

Answer 2

-2 because the difference between 8 and 10 is 2.
