<PRE><B>Question 411174</B>
figure out the surface area of the solid right circular cylinder with 
r = 9cm and h = 7cm 
Would my surface area be 904.3cm^2 
----
Surface area = side + 2*ends
side area = perimeter * height = 2(pi)9*7 = 126pi cm^2
2 ends = 2[pi*9^2] = 162pi cm^2
----
Total surface area = 288pi cm^2 is approximately 904.78 cm^2
