Answer:

We have,

Diameter = 28 cm

Height = 20 cm

Radius = 28/2 = 14 cm

Now,

Total surface area = (2πr² + 2πrh) sq. unit

= (2×22/7 × 14² + 2×22/7×14×20) cm²

= 2992 cm²

Hence,

\underline {\bold {Total~surface~area~of~cylinder}}

Total surface area of cylinder

\underline {\bold { =~2992~cm^2}}

= 2992 cm
