To find the surface area of a cone, we need to calculate the lateral surface area and add it to the base area.
The lateral surface area of a cone is given by the formula:
A_lateral = Ο * r * l
where r is the radius and l is the slant height.
Since the slant height is given as 11 units, and the radius is not given, we cannot calculate the exact surface area without knowing the radius.
However, if you provide the radius of the cone, I can help you calculate the surface area.
What is the surface area of the cone? Use 3.14 for pi and round to the nearest tenth, if necessary. The slant height is 11 units and the radius.
