We have to find the slant height? if yes then here is the answer when the semicircle is folded from the centre of the diameter then a cone is formed.. and since the diameter is 28 so the radius of the semicircle will be 14... also the radius of the semicircle is the slant height of the cone... therefore the slant height is 14 cm..hope it helps :)
