volume = base area x height
  where, base area = pi* radius^2 = pi * 0.25^2 = .0625* pi ,  or about  0.196, and 0.20 to the nearest                hundredths 
  and  height = 2,
therefore, Volume =  0.196*2,  or about 0.392 and 0.39 cubic ft to the nearest hundredths
 
Surface area = base area + top area + mid rectangular area
  base area = top area = 0.196
  mid rectangular area = circumference x height 
                                = 2*pi* radius = 2*pi*0.25 = 0.5*pi = 0.157
  Adding all,  0.196+0.196+0.157= 0.549, or 0.55 sq ft to the nearest hundredths
