John's farm silo is a right cylinder that is 35 feet high. Both the top and bottom base have a diameter of 22 feet. What is the approximate surface area of the metal used to make the silo?

The two circular ends will each have the area of the circle 2 x pi r^2 ft_{2 } r = 11 ft

the cylindrical sidewall will have an area of pi d h ft^{2} d = 22 ft h = 35 ft plug and chug !
