Step-by-step explanation:
The total surface area of a cone is given by:
Surface area =
where r is the radius of the cone, h is the height of the cone, l is the length of the cone =
Given that h = 136 mm, r = 60 mm /2 = 30 mm, l = 140 mm. Also the top of the cone is not included in the surface area, hence the surface area becomes:
