Find the slant height of a frustum cone whose top radius is 5 m and bottom radius is 12 m. The height of the cone is 24 m.

The larger and smaller diameter of a cone is 35 m and 15 m. The slant height of the cone is 210 m. What is the surface area of a frustum of cone? 
(Use $$\pi$$ = 22/7). 

The larger radius of a frustum cone is thrice the smaller radius which is 12 m. The slant height of the cone is 120 m. What is the surface area? (Use $$\pi$$ = 3.14). 

The larger radius of a frustum cone is double the smaller radius which is 12 in. The slant height of the cone is 40 in. What is the surface area? (Use $$\pi$$ = 3.14).

The smaller diameter of a frustum cone is thrice the larger radius which is 4 in. The slant height of the cone is 13 in. What is the surface area? (Use $$\pi$$ = 3).
