Surface area of a cone:
r = radius of circular base
h = height
s = slant height
Surface area = π * r * (r + √(r² + h²))
If you know the "slant height", the formula becomes a bit cleaner.
Surface area = π * r² + π * r * s

л r^2 + л rs where r is the radius of the base and s is the slant height. If you don't want to include the base then eliminate the first term.

Surface area of cone=3.1415xradiusx(radius+side height)
Volume=3.1415x(radius square)xstraight height / 3
pai=3.1415
