A cone with height 8 and radius 2 is sliced halfway along its height by a plane that is parallel to the base of the cone. What is the radius of the circle at the intersection of the plane and the cone?

Answer:

1

Step-by-step explanation:

The cone is sliced by a plane, which produces a smaller cone on top.  This cone is similar to the original cone.  Therefore:

R / H = r / h

2 / 8 = r / 4

r = 1
