Question

find the volume of a surface area of the solid formed by a revolving a right angled triangle about a side adjacent to the right angle. what is the solid so obtained?

Answer 1

Hi friend,
______________________________________________________________________________________________________________________________when we revolve a right angled triagle about a side adjecant to the right angle we got a Cone .
______________________________________________________________
volume of cone =1/3πr²h
_____________________________________________________________

Answer 2

On revolving a right angled triangle about the side adjacent to right angle you get a cone.

So the volume of the cone with radius 'r' and height 'h' is
1/3πr²h

Hope This Helps You!
