a solid metallic right circular cone 20 cm high with vertical angle 60 is cut into two parts at the middle point of its height by a plane parallel to the base. its frustum, so obtained be drawn into a wire if diameter 1/16 cm, find the length of the wire .
Radius (r1) of upper end of frustum =
Radius (r2) of lower end of container =
Height (h) of container = 10 cm
Volume of frustum =
Radius (r) of wire =
Let the length of wire =l.
Volume of wire = Area of cross-section × Length
= (πr2) (l)
Volume of frustum = Volume of wire
