<PRE><B>Question 205532</B>
Find the surface area of a cylinder in terms of pi with a radius of 8 in and a height of 11 in; a cylinder with a diameter of 14 cm and a height of 15 cm; and a cylinder with a radius of 28 cm and a height of 48 cm.
--------------
Area = 2pi*r*h + 2pi*r^2
Area = 2pi*r(h + r)
-------------
radius of 8 in and a height of 11 in
Area = 16pi*19 = 304pi in^2
----------------
diameter of 14 cm and a height of 15 cm
Area = 2pi*7(15+7)
Area = 308pi cm^2
---------------
r or 28 cm and a height of 48 cm
Area = 2pi*28*76
Area = 4256pi sq cm</PRE>
