If the height of a cone is cut in half, the volume of the cone is multiplied by what number?

The volume would be multiplied by 1/2 as well.

The volume of a cone is given by the formula

V = (1/3) πr²h.

Replacing h with (1/2) h, we have

V = (1/3) πr² (1/2) h

Using the commutative property, we can rewrite this as

V = (1/3) (1/2) πr²h

V = (1/6) πr²h

This is the same as multiplying the volume by 1/2.
