Question

1) A metallic right
Circular cone 20 cm high and
whose vertical angle in 60 degree is cut into two parts
at the middle of its height by a plane parallel to
it's base if the frustum so obtained be drawn into a wire of diameter 1/16 cm, find the length of the wire​

Answer 1

HELLO

HERE IS UR ANSWER :

Answer:

7964.4m

Step-by-step explanation:

Let given cone is OCD

and ABCD be the required frustum

Since frustum is drawn into wire

Volume of frustum ABCD = Volume of cylindrical wire

Given OP=20cm

and half height of frustum =10cm=OQ=QP

also Angle QOB=60 degree

We need to find the radius of base and top of the frustum
