chris from yahoo answers said this and i agree kinda
The area will be:

TOP OF CAKE

=pi*r*r= 22/7*9/2*9/2=891/14=445.5/7=63.2 inches^2

SIDE OF CAKE

=2*pi*d*h=2*22/7*9*5=180*11/7=1980/7= 282.8 inches^2

ADD TOGETHER

=2425.5/7= 346.5 inches^2

May be slightly off because of mental arithmetic
