A right triangle with sides 6cm,8cm and 10cm is revolved about the side 8cm.Find the volume and curved surface area of solid so formed.
The given triangle is revolved around the side 8 cm and hence the radius of our new cone(r) = 6cm and height (h) = 8 cm. Volume of cone=301.71 Curved surface Area=prl Thanks & Regards, Vasantha Sivaraj, askIITians faculty.
