Cone and Frustum

A right circular cone is sliced into a smaller cone and a frustum of a cone by a plane perpendicular to its axis. The volume of the smaller cone and the frustum of the cone are in the ratio 64 : 61. Then their curved surface areas are in the ratio

A right circular cone, with radius and height 8 and 6 respectively , is cut parallel at the middle of the height to get a smaller cone and a frustum. By what percentage, to the nearest integer, is the combined total surface area of the smaller cone less than of the frustum?

A cone is having its base radius 12 cm and height 20 cm. If the top of this cone is cut in to form of a small cone of base radius 3cm is remove, then the remaining part of the solid cone becomes a frustum. Calculate the volume of the frustum.
