Answer:
What is the difference between curved surface area and total surface area?
Consider a cylinder. You have a curved surface and two circles,one at the bottom
and one at the top.
As far as curved surface area is concerned we find the curved portion area= 2π∗r∗h
But when we want to find the total surface area, along with the curved surface
area we include the areas of two circles{present in both ends}=
2π∗rh+2π∗r2
As far as a cone is concerned we have only one circle at the base for calculating
total surface area [formula for total surface area=[math]\pi*r{l+r)[/math]
As far as hemisphere is concerned we have a circular area at the top[like 1/2 coconut] Its total surface area is 3 π∗r2
