Question

A right angled triangle is revolved about its hypotenuse which sides are 6,8,10cm.find the volume of this cone

Answer 1

Answer:

Step-by-step explanation:

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
