Step-by-Step Solution
Small cone is half the height, so its linear scale is and volume scale is of the full cone. Frustum = . Ratio small : frustum = .
Answer: A) 1 : 7
A cone of height 20 cm is divided into two parts by a plane through the mid-point of its axis, parallel to the base.
Find the ratio of the volume of the upper small cone to the volume of the lower frustum.
