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
