The formula for total surface area of a cylinder is ...
total area = total base area + lateral area
= 2(base area) + lateral area
= 2(πr^2) +2πrh
= 2πr(r +h)
This formula has been put into the attached spreadsheet so it can do the arithmetic. You will notice that we left out the factor of pi, because we want to use the symbol to represent its exact value. Note, too, that the radius is half the diameter.
The areas are ...
1) 36π square inches
2) 460π square feet
3) 216π square yards
