Answer:

Step-by-step explanation:

radius=r/2,

slant height = 2l.

total surface area of cone =πr(l+r)

                                               =22/7  ×r/2(r/2  +  2l)

                                               =11r/7[(r+4l)/2]

                                                 =        [11r(4l+r)]/14
