The roof of a grain silo is shaped like a right circular cone. The amount of paint needed to weather seal the roof is proportional to the lateral surface area of the cone. If the circular base of the cone has a radius of 35 feet and the perpendicular distance from the vertex of the cone to the center of the base is 12 feet.

I have a cones geometry question.

The roof of a grain silo is shaped like a right circular cone. The amount of paint needed to weather seal the roof is
proportional to the lateral surface area of the cone. If the circular base of the cone has a radius of 35 feet and the
perpendicular distance from the vertex of the cone to the center of the base is 12 feet.
What is the lateral surface area of the cone in square feet?
