The height of a cylinder is 80 cm and the diameter of its base is 7 cm. The whole surface area of the cylinder is
We know that,
Total surface area of the cylinder = 2
(r + h)
Given that,
Diameter = 7 cm
So, Radius = 3.5 cm
Height = 80 cm
Therefore,
Total surface area = 2 × 
× 3.5 (3.5 + 80)
= 22 (83.5)
= 1837 cm2
Hence, option A is correct
