For the right circular cone shown, \( OP \) is a radius of the base and V is the vertex. The cone's lateral surface area, in square meters, is \( rLπ \) , where r  is the length, in meters, of \( OP \) and L is the length, in meters, of \( VP \). The cone has a base area of \( 36π \) square meters and a lateral surface area of \( 143π \) square meters. What is the height of the cone, to the nearest meter?
