Answer:

Option B

Explanation:

Surface area of a cone is given by the expression,

V = πr(r + l)

Here, r = Radius of the circular base

l = Lateral height of the cone

By substituting the given values in the given expression of volume,

V = π(8)(8 + 15)

= 184π units²

Therefore, surface area of the given circular cone is 184π units².

Option B is the correct option.
