Question 708294
The three parts are:

The cone.
You would like the height.  Not really needed, since area without the circular bottom is simply pi*r*(slant height), or {{{pi*0.7*2*0.7}}}.

The cylinder.
You have the radius and you need the circumference.  Surface area for this part is {{{2*pi*0.7*10.7}}}.

The hemisphere.
For a sphere, s.a. is 4*pi*r^2.  For this exercise, the HEMISPHERE has s.a. of {{{2*pi*0.7^2}}}.


Part of my process included{{{ pi*0.7*(1.4+2*10.7+2*0.7)}}}

Find the sum of those three.  What do you get?
My result is 53.21 cm^2.   Or 53.2 cm^2
