Hi !
T.S.A of cone = π*radius + (radius + slant height)
radius = r/2
slant height = 2 l
T.S.A = π*r/2(r/2 + 2l)
= πr/2 ( r + 4l/2)
= {πr(r +4l)}/4
T.S.A of the cone is {πr(r +4l)}/4
T.S.A of cone = π*radius + (radius + slant height)
radius = r/2
slant height = 2 l
T.S.A = π*r/2(r/2 + 2l)
= πr/2 ( r + 4l/2)
= {πr(r +4l)}/4
T.S.A of the cone is {πr(r +4l)}/4
