Curved (lateral) surface area = (External surface area)+(Internal surface area)=`2 pi R h + 2 pi r h = 2 pi h (R + r)`sq. units.

Curved (lateral) surface area = (External surface areal) (Internal surface area)= 2 pi Rh+2 pi rh=2 pi h(R+r)sq. units.

Total surface area quad =2 pi Rh+2 pi rh+2 pi(R^(2)-r^(2))

Total surface area =(2 pi rh+2 pi r^(2)) sq.
