Question

A right triangle with sides 6cm, 8cm, 10cm is revolved around about the side 8cm. Find the volume and curved surface area of the solid formed

Answer 1

The cone so formed has h= 8cm as the height and base radius as r= 6cm and slant height as l=10cm

 volume =1/3h

            =1/3*3.14*6*6*8

            =301.44cubic cm

curved surface area=rl

                               =3.14*6*10

                               =188.4 square cm
