Surface Area Formula: A=2πrh+2πr^2
Nam's Cylinder:
Diameter = 7 inches
Height = 13 inches
Radius=Diameter/2 = 3.5
Bradon's Cylinder:
Diameter = 5 inches
Height = 20 inches
Radius=Diameter/2 = 2.5
Nam's Cylinders Surface Area:
SA=2πrh+2πr^2
SA=2π(3.5)(12)+2π(3.5)^2
SA≈340.8628inches^2
Bradon's Cylinders Surface Area:
SA=2πrh+2πr^2
SA=2π(2.5)(20)+2π(2.5)^2
SA≈353.42917inches^2
Nam's cylinder's surface area is approximately 341inches^2 and Bradon's cylinder's surface area is approximately 353inches^2.
Therefore, Bradon's cylinder has the larger surface area.
