designing a paper cup
a) approximate S to the nearest hundredth when r=1.5 inches and h= 4 inches
-------------
If h is the distance on the center line, and not the slant height,
Find the slant height:
s+=+sqrt%281.5%5E2+%2B+4%5E2%29+=+2.5
Lateral area = pi%2Ar%2As+=+10%2Api sq inches
That does not include the area of the bottom.
