area of the bases

2 r2=2 784=1568

circumference of base

2 r=56

extension of the height

2 r h=56 48=2688

bases plus nonbase surface are total surface

1568 +2688 =4256

Solution:

radius= 28 cm

height = 49 cm

A = 2pirh+2pir2

A = (2×3.14×28×48)+(2×3.14×28^2)

A = 13370.61833cm^2

Surface area of cylinder is 13,370.62 cm^2.
