What is the Area of a Right Circular ConeIf r, h and ℓ denote respectively the radius of base, height and slant height of a right circular cone, then-ℓ 2 = r2 + h2 Area of base = πr2 Curved (lateral) surface area = πrℓ Total surface area = πr (ℓ + r) Volume = πr2hRead more about Radius of a Right Circular … [Read more...] about What is the Area of a Right Circular Cone
