Step-by-step explanation:
The surface area of a right circular cone is SA =<span>

</span>
The diameter (d) is equal to 20 meters and half of it is equal to the radius which is 10 meters.
The height (h) of the tank is equal to 42 meters.
Substituting the given to the equation:
SA =

= 1670.51 square meters or the closest answer is 1,671 m2
