Answer:
Volume of smaller cone =301.44
Step-by-step explanation:
First let angle of cone be.
then = 3/5 (For bigger triangle)
Same cone angle is for smaller one because they are similar.
= 4/5
Now for smaller cone radius be R
3/5 =R/Slant height
Slant height =5/3R
Lateral surface area = [R = slant height]
Given lateral surface area =60 =
...................................1
................................................2
Put angle beta in equation 1 and find the value of R
R =6 cm
Height =
Thus volume =
=301.44
