Calculate the surface area of the figure given below in hectares given that the radius is 14 m and the height is 20 m.
A: 1232 cm²
B: 1760 cm²
C: 1188 cm²
D: 2992 cm²
Surface area of a cylinder=area of two circles+Area of curved surface
Surface area of a cylinder=2(πr²)+πdh
=2(22/7×14²)+22/7×28×20
=1232+1760
=2992 cm²
