For a science project, students need to build a cone-shaped model. The teacher says the
radius and height of a right circular cone are in the ratio of 5: 12. The model should also
have occupied the space of 1,07,800 cm³.
I) Find the slant height of the cone-shaped model.
ii) Calculate the curved surface area of the cone-shaped model.
iii) Determine the total surface area of the cone-shaped model.
