Q : 7 A right triangle ABC with sides 5 cm, 12 cm and 13 cm is revolved about the side 12 cm. Find the volume of the solid so obtained.
When a right-angled triangle is revolved about the perpendicular side, a cone is formed whose,
Height of the cone = Length of the axis=
Base radius of the cone =
And, Slant height of the cone =
The volume of a cone =
The required volume of the cone formed =
Therefore, the volume of the solid cone obtained is
