FAQs
What is the difference between curved surface area and total surface area of a cone?
Curved surface area of cone = π r l. Total surface area = π r l + π r^2 (curved surface + circular base).
How do I find the surface area of a cylinder?
Surface area of cylinder = 2π r h (curved surface) + 2π r^2 (two circular bases) = 2π r(r + h). Alternatively, 2π r^2 + 2π r h.
