How To Calculate Conical Frustum Volume?

Conical Frustum Volume = 1/3 * π * height * (top radius²+ top radius * bottom radius + bottom radius²) ,
ex : top radius = 15, bottom radius = 20, height = 30 . Volume = 1/3 * π * 30 * (15² + 15 * 20 + 20²)= 29059.732 m³ .

Calculate Conical Frustum Area?

Area =π * [ Top Radius² + bottom Radius²+ (Top Radius + Bottom Radius) * √(Top Radius - Bottom Radius)² + height²)] .
Top area =π * Top Radius².
Base area =π * Bottom Radius².

Slant height =√(Top Radius - Bottom Radius)² + height²).
