Question 215315
Area  of  cylinder  = area  of  top and  bottom  and  side
.
A= 2(pi*r^2) + (2*pi*r*h)
.
A= 2pi(18)^2 + 2pi(18)(30)
.
A= 2035.75 + 3392.92
.
A= 5428.67  m^2
.
.
Cost = 5428.67 m^2 * 4.5 # / 6m^2 = 4071.5025 #
.
.
If  we  do  not  paint  bottom,,A=pi * 18^2 = 1017.876 m^2
.
subtract ,,,,cost  = 1017.876 * 4.5/6 = 763.41 #
.
The  total (without bottom) = 3308 #
.
