A metallic cone of base radius 6 cm and height 9 cm is cut by a plane parallel to its base at the midpoint of its height. Find the radius of the smaller (top) circular face of the frustum left below the cut, in cm.

Question

Accepted Answer

3. By similar triangles, radius at half the height = 1/2*base radius = 1/2*6 = 3 cm.

A metallic cone of base radius 6 cm and height 9 cm is cut by a plane parallel to its base at the midpoint of its height.
Find the radius of the smaller (top) circular face of the frustum left below the cut, in cm.
