In this question why did we use volume why not TSA or CSA for frustum and cylinder please explain why did we use volume, no need of solution.   A metallic right circular cone 20 cm high and whose vertical angle is 6Cr is cut into two parts at the middle of its height by a plane parallel to its base. If the frustum so obtained is drawn 22 into a wire of diameter —cm, find the length of the wire. Use 16

When we convert one solid figure to another solid figure we use the formula of volume .Note:Volume of a solid object is the measure of the space occupied by it.
