Surface Area:
Surface Area = 2πr2 + 2πrh
= 2π(3.5 ft)2 + 2π(3.5 ft)(14 ft)
= 2π(12.25 ft2) + 2π(49 ft)
= 24.5π ft2 + 98π ft2
= 122.5π ft2
= 384.7 ft2 (to the nearest tenth of a foot)
Volume:
Volume = πr2h
= π(3.5 ft)2(14 ft)
= π(12.25 ft2)(14 ft)
= 171.5π ft3
= 545.2 ft3 (to the nearest tenth of a foot)
