Question

what is the curved surface area (c.s.a)and total (t.s.a.)of a right circular cone​

Answer 1

Answer:

For a right circular cone of radius 'r', height 'h' and slant height 'l', we have; Curved surface area of right circular cone = π r l. Total surface area of a right circular cone = π(r + l) r. Volume of a right circular cone = 1/3π r2 h.

Step-by-step explanation:

The curved surface area of a right circular cone equals the perimeter of the base times one-half slant height. The total surface area equals the curved surface area of the base.
